5 characteristics of refraction
Characteristics of refraction: When light travels from one medium to another, the frequency of light does not change. However, the velocity and wavelength change.
When travelling from one optical medium to another with different refractive indices, a ray of light bends. The ratio of sine of angle of incidence to the sine of angle of refraction is a constant for a given pair of media.
When a ray of light travels obliquely from an optically rarer medium to an optically denser medium,it bends towards the normal at the point of incidence. in this case,angle of incidence is greater than the angle of refraction...
