Question

Answer

Its refraction yrr.. This is a common definition of refraction that u r asking 🤦🏻‍♂️

Answer

This 'bending of a ray of light' when it passes from one substance into another substance is called refraction. The bending of a ray of light also occurs when the ray comes out of glass or water and passes into air.

Answer

Correct answer is A because this is same as glass slab.

Answer

Refraction is the bending effect of light as it passes from one transparent material into another. When light travels from one medium to another, such as from air to water or from air to glass, its speed changes and this change in speed causes the light to change direction. This phenomenon is known as refraction.

Explanation:

1. Definition of Refraction:
- Refraction is the bending of light as it passes from one medium to another.
- It occurs due to the change in speed of light when it travels from one medium to another.

2. How Refraction Works:
- When light passes from one medium to another, such as from air to water, it changes speed.
- This change in speed causes the light to bend or change direction.
- The amount of bending depends on the refractive indices of the two media.
- Refractive index is a measure of how much light is slowed down or sped up when it passes through a medium.

3. Snell's Law:
- Snell's law describes the relationship between the angle of incidence and the angle of refraction.
- According to Snell's law, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the speeds of light in the two media.
- This relationship can be mathematically expressed as n1sinθ1 = n2sinθ2, where n1 and n2 are the refractive indices of the two media, and θ1 and θ2 are the angles of incidence and refraction respectively.

4. Examples of Refraction:
- When a pencil is partially immersed in a glass of water, it appears bent at the water-air interface due to refraction.
- The bending of light in a prism is another example of refraction, where light is dispersed into its constituent colors.
- The formation of rainbows is also a result of refraction and the dispersion of light.

5. Importance of Refraction:
- Refraction plays a crucial role in various optical devices such as lenses, microscopes, and telescopes.
- Corrective lenses used in eyeglasses rely on refraction to help focus light onto the retina.
- Refraction also allows us to see objects underwater, as the light rays bend when they pass from water to air, enabling us to see objects that are otherwise hidden.

In conclusion, the bending effect of light as it passes from one transparent material into another is known as refraction. It occurs due to the change in speed of light when it travels from one medium to another and plays a significant role in various optical phenomena and devices.
