Question

Light refracts due to a change in blank:

A) Volume
B) Energy
C) Intensity
D) Speed
E) Amplitude

Answer 1

it answer will be D) speed because due to change in the speed of the light during it pass through one medium to another the light started bending and cause refraction.

Answer 2

Light refracts due to a change in Speed.

Option: D

Explanation:  

• Whenever there is a change in the medium the 'rays of the light refract'. Refraction is the change in the path of light when light travels from one transparent medium to another transparent medium.  

• Refraction of light is due to the 'change in the speed of light' along with the wavelength of light due to the change in the medium.  

• The frequency of light remains the same. As a result when light travels from air to another medium which is optically denser than air the rays of light travel at a slower speed as compared to the speed of light in air.
