Glass is a perfect everyday example of light refraction. Looking through a glass jar will make an object look smaller and slightly lifted. If a slab of glass is placed over a document or piece of paper, then the words will look closer to the surface because of the different angle the light is bending.

Refraction is the bending of a light or sound wave, or the way the light bends when entering the eye to form an image on the retina. An example of refraction is a bending of the sun’s rays as they enter raindrops, forming a rainbow.

Meters like ammeters and voltmeters use a mirror to avoid parallax error. The rear-view mirror enables the driver to see things behind the car. A microscope uses a mirror to reflect light to the specimen under the microscope.

Two main types of reflection are often referred to – reflection-in-action and reflection-on-action. The most obvious difference is in terms of when they happen.

These are:

• An object placed under water appears to be raised.
• A pool of water appears to be less deep than it actually is.
• The stars appear twinkle on a clear night.
• A stick held obliquely and partly immersed in water appears to be bent at the water surface. Answer verified by Toppr. Related questions.

If the angle of incidence is zero then it means the light Ray is travelling perpendicular to the medium hence there would be no refraction and the angle of refraction would also be zero. If the angle of incidence is zero, then the light passes undeviated. Hence the angle of refraction will be zero.

: the angle between a refracted ray and the normal drawn at the point of incidence to the interface at which refraction occurs.

Common objects include mirrors (reflect); glass of water with spoon in it (refract); foil (reflect); oil in a glass bottle (refract); prism (refract); glass (refract); lens (refract); or any shiny surface (reflect).

Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.

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.

Light refraction occurs when something gets in the way of the light waves. Because the light can’t travel as quickly in the water as it does in the air, the light bends around the pencil, causing it to look bent in the water.

Answer: If you put it in a clear glass you will see a bigger size of fork while if you put it out the fork will be normal in size because the molecules or lens will expand and created images that take the fork big as you look.
