Question

1. In case of refraction of light.
) frequency changes
A
30
16) ghase changes
) speed charges
D) wave length does not change how​

Answer 1

Answer:

D wave length doesn't change

Answer 2

Answer:

speed changes

Explanation:

In refraction speed of light and wavelength of light changes. In a medium speed of light is given by v=

μ

c

where μ is refractive index of the medium. In refraction wavelength also changes because energy remains constant
