The phenomenon of bending light when it passes through one transparent medium to another is due to _________________.

Correct option is B

The correct answer is (B) Refraction.

Explanation:
Refraction is the phenomenon that occurs when light passes from one transparent medium to another, causing it to bend. This bending happens due to a change in the speed of light as it moves from one medium to another. The amount of bending depends on the refractive index of the two media. For example, when light moves from air (less dense) into water (denser), it slows down and bends towards the normal.

Information Booster:

• Refraction occurs because the speed of light is different in different media. For example, light travels slower in water or glass than in air.

• Refractive index is a measure of how much light slows down in a medium compared to its speed in a vacuum. Higher refractive index means greater bending of light.

• Snell’s Law describes the relationship between the angles of incidence and refraction for light passing through different media.

• Common examples of refraction include the bending of light when it enters water, causing objects to appear distorted, and the formation of rainbows due to light passing through raindrops.

Additional Knowledge:

• Scattering: This occurs when light interacts with small particles or molecules in the medium, causing the light to spread in different directions. It is responsible for phenomena like the blue sky.

• Diffraction: This is the bending of light around obstacles or through small openings, leading to interference patterns.

• Reflection: This is when light bounces off a surface rather than passing through it. Reflection occurs at the boundary between two media, such as light reflecting off a mirror.
