A spoon which seems tilted in water, is an example of:. – It is the phenomena of bending of light when it changes its medium of propagation from one transparent medium to another transparent medium.

(frac{{Sin;i}}{{Sin;r}} = ;frac{{{n_2}}}{{{n_1}}}). If the above ratio is more than one, then the light will bend toward the normal and if it is less than one, the light will bend away from the normal.

the higher the optical density, the lower the speed of light. This change in speed causes light to bend (refract), as can be seen when a spoon is put into a glass of water
This bending of the light is referred to as refraction. Refraction of light as it passes from one medium to another can be calculated from Snell’s Law

### Physics Tutorial: Refraction and Sight [5]

In Unit 13 of The Physics Classroom Tutorial, it was emphasized that we are able to see because light from an object can travel to our eyes. Every object that can be seen is seen only because light from that object travels to our eyes
In the process of viewing Mary, you are directing your sight along a line in the direction of Mary. If you wish to view the top of Mary’s head, then you direct your sight along a line towards the top of her head
And if you wish to view the image of Mary in a mirror, then you must direct your sight along a line towards the location of Mary’s image. This directing of our sight in a specific direction is sometimes referred to as the line of sight.

### Refraction of Light [7]

As we all have noticed at one time or another, a pool of water appears to be shallower than it really is and a spoon seems to bend or even break when we use it to stir a glass of lemonade (Figure 17.9a). The reason for these seemingly strange phenomena is the fact that light travels at different speeds through different transparent media because the electromagnetic waves interact with the matter of the medium in which they travel
The speed of light in air is about 299,900 km/s, nearly the same as in vacuum. The oscillating electric field of the electromagnetic wave sets the electrons of the atoms and molecules that make up the medium through which light is propagating into vibration
It is this constant absorption and re-emission of electromagnetic energy that gives the appearance that light has slowed down, although it is still traveling between interactions with the electrons at 300,000 km/s as it does in vacuum, where there are no electrons to interact with.. A ray of light from a point on a spoon under the water travels along the water in a straight line at 225,000 km/s until it encounters the boundary between water and air (Figure 17.9b)

A spoon half-immersed in a glass of water appears bent at the surface of the water. We know that this is due to refraction of light, which bends the rays of light at the surface, so that the retinal image of the spoon is illusorily bent

### Simple Refraction of Light Science Experiment – Can Water Bend a Straw? [9]

What do you think, can water bend a straw? What about other clear liquids? In this super simple science experiments, kids will learn about the refraction of light, and why a straw appears to be bent when submerged in a glass of liquid.. Find printable instructions, a video demonstration, and a helpful explanation of how this experiment works, below.
Make a few more observations and point out that the straw is still straight.. Helpful tip: Use a large plastic straw from a water bottle to see the results more clearly.

### Refraction [10]

In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave’s change in speed or by a change in the medium.[1] Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction
For light, refraction follows Snell’s law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence and angle of refraction is equal to the ratio of phase velocities in the two media, or equivalently, to the refractive indices of the two media:[2]. Optical prisms and lenses use refraction to redirect light, as does the human eye
This is called dispersion and causes prisms and rainbows to divide white light into its constituent spectral colors.[4]. Refraction of light can be seen in many places in our everyday life

### Mirror Image: Reflection and Refraction of Light [12]

When people look into a mirror, they see an image of themselves behind the glass. That image results from light rays encountering the shiny surface and bouncing back, or reflecting, providing a “mirror image.” People commonly think of the reflection as being reversed left to right; however, this is a misconception
The mirror does not reverse the image left to right; it reverses it front to back. For example, if you are facing north, your reflection is facing south.
Geometric optics is one of two broad classes of optics, the field that “deals with the propagation of light through transparent media,” according to Richard Fitzpatrick, a professor of physics at the University of Texas at Austin, in lecture notes for a course in Electromagnetism and Optics. Geometric optics treats light as continuous rays (as opposed to waves or particles) that move through transparent media according to three laws

### Knowino [13]

Light, also known as visible light, is electromagnetic radiation visible to the human eye.. Light, like all electromagnetic radiation, consists of photons
Intensity is not a property of the photons, but rather their number.. Visible light makes up only a small portion of the electromagnetic spectrum
Light exhibits behavior characteristic of both waves and particles. Until recently it was deemed impossible to detect both the particle nature and the wave nature of light at the same time, as they were believed to be two representations of the same phenomenon

It is difficult or not possible to break spoon with hands. What if I break spoon first and bring it back to its original straight shape? Believe me it is very easy
What do you see? Spoon is back to its original and it is not broken.. If you observe carefully, you will notice that, spoon appears broken only near the surface of the water; however it is seen continuous without any breakage inside the water

### Engineered Metamaterials Can Trick Light and Sound into Mind-Bending Behavior [16]

Electromagnetic waves bring radio, television and endless streaming content to our devices. Remarkably, all these different waves are governed largely by the same fundamental physical principles
The Greek prefix meta means “beyond.” These engineered materials let us move beyond the traditional ways in which waves and matter interact, creating technologies where light and sound appear to disobey conventional rules. The marquee example of this new style of materials is the “invisibility cloak”—a metamaterial coating that can hide an object in plain sight
Although these inventions have limitations—they aren’t quite the Harry Potter–style invisibility cloaks that many people imagine—they nonetheless interact with light in a way that seems like magic.. Cloaks are just one example of metamaterial technology

### New class of laser beam doesn’t follow normal laws of refraction [17]

University of Central Florida researchers have developed a new type of laser beam that doesn’t follow long-held principles about how light refracts and travels.. The findings, which were published recently in Nature Photonics, could have huge implications for optical communication and laser technologies.
The beams, known as spacetime wave packets, follow different rules when they refract, that is when they pass through different materials. Normally, light slows down when it travels into a denser material.
“As such, these pulses of light can arrive at different points in space at the same time.”. “Think about how a spoon inside a water-filled glass looks broken at the point where the water and air meet,” Abouraddy says

### Essential Question: What are the different types of wave interactions? [18]

Essential Question: What are the different types of wave interactions?. Changes in Mediums Waves do not just stop when they reach the end of a medium or when they meet an obstacle in the path
We will be examining these behaviors in regards to waves. Changes in Mediums: When waves strike an object, some of the waves are absorbed by the object, some are reflected by it, and some might pass through it (transmitted)
Absorption is the transfer of light energy to matter Absorbed light can make things feel warmer Think of examples of light absorption that you have experienced. When a beam of light shines through the air, particles in the air absorb some of the energy from the light
