Question

what do you understand by refraction of light. draw the labelled ray diagram, when ray of light passes through glass slab.

Answer 1

Answer:

Explanation:

Reflection of light means bending of light rays because of change in medium as well as because of change in speed of light.

Answer 2

Answer:

A light ray deviates from its intended course when it passes through one medium and then another. The term "refraction of light" refers to this occurrence.

Explanation:

Cause of Refraction:

• In comparison to rarer media, such as air, the speed of light is slower in denser medium, such as glass. This suggests that light's speed slows down as it transitions from a rarer medium into a denser one.
• On the other hand, light's speed increases when it transitions from a denser to a rarer medium. Therefore, refraction of light is a phenomena that occurs as a result of the speed differential between one medium and another.
• The light's refraction occurs when a light ray enters an object with a differing refractive index at an angle. When a refracted ray's intensity is lower than an incident ray's intensity, refraction occurs.
• When a light beam moves obliquely from a rarer to a denser medium, it bends towards the normal.
• Glass is heavier than air, thus when a light beam passes through a rectangular glass slab, it bends towards the normal after the first refraction and away from the normal after the second refraction.

Thus, light bends toward the normal as it moves from a rarer to a denser medium. Additionally, light deviates from the standard as it moves from a denser to a rarer medium.
