Question

(v) The phenomenon in which a ray of light, travelling from one optical medium
another optical medium, bounces off from its surface with the change of angle
is called refraction of light. Correct the statements. ​

Answer 1

Answer:

The phenomenon in which a ray of light, travelling from one optical medium

another optical medium, passes through the surface with the change of angle

is called refraction of light

Answer 2

Corrected Sentence:

The phenomenon in which a ray of light, travelling from one optical medium to another optical medium, bounces off from its surface with the change of angle is called reflection of light.

$\large{ \boxed{ \bf{ \pink{Refraction \longrightarrow \: Reflection}}}}$

Explanation:

When a light ray or a beam of light on a reflective polished surface, it bounces off from the same medium. This depends on the surface only, whether it is rough or a polished surface.

• Depending upon this, the light is absorbed or reflected or transmitted.

Whereas,

Refraction is the phenomenon in which direction of light changes due to bending when light enters from one medium to another. This is occurs because of different speeds of light in different media.

• Optical rarer medium is the one in which speed of light is more.
• Optical denser medium is the one in which speed of the light is less.
