Question

define refraction, Dispersion of light, and angular dispersion.​

Answer 1

Explanation:

Refraction:change in direction of propagation of any wave as a result of its travelling at different speeds at different points along the wave front.

Dispersion of light:The dispersion of light is the phenomenon of splitting of a beam of white light into its seven constituent colours when passed through a transparent medium.

Angular dispersion:The angular dispersion is defined as angle between the two extreme colours of light (i.e. violet and red colours).

Answer 2

Answer:

Refraction

The change in a direction of wave passing from one medium to another caused by it's change in speed.

Dispersion of light

The dispersion of light is the phenomenon of splitting of a beam of white light into it's seven constituent colour passing Through a transparent medium.It was discovered by Issac Newton in 1666.

Angular dispersion

Angular dispersion is defined as angle between two extreme color's of light.
