1] . Fill in the blanks
Refractive inden depends on the of light.
z] The change in of light stays while.foing from
ane medium to another is called refraction
​

Answer 1

Answer:

Wavelength .

Explanation:

1. Refractive index depends on the wavelength of light. This change in the speed of light causes it to bend, which is simply referred as refraction. Higher the change in wavelength higher will be refraction. Hence the refractive index of the medium is directly dependent on the wavelength.
2. Refraction is the change in direction of a wave passing from one medium to another caused by its change in speed. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media.
