ii. The refractive index depends upon the…………of propagation of light in different media.

iii. The process of separation of light into its component colours while passing through a medium is called………..

iv. When a light ray travels obliquely from air to water, it bends………the normal at the point of incidence.

v. When a light ray travels obliquely from benzene to air, it bends…………the normal at the point of incidence.

Answer 1

i. The phenomenon of change in the direction of propagation of light when it passes obliquely from one transparent medium to another is called refraction.

ii. The refractive index depends upon the velocity of propagation of light in different media.

iii. The process of separation of light into its component colours while passing through a medium is called dispersion of light.

iv. When a light ray travels obliquely from air to water, it bends towards the normal at the point of incidence.

v. When a light ray travels obliquely from benzene to air, it bends away from the normal at the point of incidence.
