Question

1) refractive index depends on the ________ of light

2) the change in _________ of light ray while going from one medium to another is called refraction​

Answer 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.
