Question

1.What is dipersion of white?

2.Explain the process when white light passes through a prism.​

Answer 1

Explanation:

a) The phenomenon of splitting of white light into its seven constituent colours when it passes through a glass prism is called dispersion of white light. ... The different component colour of light bends at a different angle with respect to the incident angle.

What is dipersion of white?

Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue and violet. The separation of visible light into its different colors is known as dispersion.

Explain the process when white light passes through a prism.

$\huge{\mathfrak{\pink{\boxed{\purple{\underbrace{\overbrace{\pink{†Answer†}}}}}}}}$

When white light is made to passes through a prism, a spectrum of seven colours is formed which shows that white light is a mixture of seven different colours. Prism only acts as a medium for the separation of the seven colours. When light falls on the glass prism, refraction takes place. Since the wavelength of different components of light is different and the frequency is constant, each component gets deviated by a different angle due to the difference in velocity in the glass medium. The red colour having the maximum wavelength deviates the least and forms the upper part of the spectrum whereas violet having the least wavelength deviates the most.

White light dispersion occurs because, as they passes through a prism, different colours of light bend through different angles with respect to the incident ray. The red light bends the least while the violet bends most as shown below.
