Question

do you think there should be any condition for the refraction of light to happen? explain in one line

Answer 1

Answer:

Yes there should be change in speed

Answer 2

For refraction to occur there must be change in the medium in the path of ray of light

Explanation:

• Refraction is the phenomena in which ray of light bend or deviate through its path when passes from one medium to another
• Refraction occurs only when there is change in medium that is ray either moves from rarer to denser medium or from denser to rarer medium
• In refraction frequency of light does not change whereas velocity as well as wavelength changes while moving through one medium to another

• When light enters from rarer to denser medium it bends towards the normal and when it moves from denser to rarer medium it bends away from the normal
