Question

During refraction, the ______________ will not change.

Answer 1

Refraction of light:-

1. In refraction of light, bending of light takes place.
2. When a ray of light travels from a rarer medium to a denser medium, it bends towards the normal.
3. Usually light travels in a straight line but after light crosses the boundary between both of the mediums, then there is a deviation that occurs in the path of the light ray.
4. This phenomenon is known as refraction.
5. There is a change in the wavelength of light if light travels from one medium to another medium.

Frequency:-

1. Frequency is the characteristic of light, which does not depend on the medium.
2. Frequency, wavelength, and speed of light are related to one another by the condition,
   $Speed=frequency\times wavelength.$
3. Since frequency does not change but there is a change in wavelength so speed also changes.

Hence, during refraction, the frequency will not change.
