Question

The light is made up of seven colours. Siya observed the spectrum of seven

colours when she incident white light on a glass prism.

(a) Name this phenomenon of splitting of white light into seven colours.

(b) Give reason for splitting of white light into seven colours in this case.

(c) Which colour bends the most in this case
fast answer on level 8th class​

Answer 1

Answer:

(a) This phenomenon of splitting of white light into seven colours is called Dispersion.

(b) Violet colour bends the most because of shorter wave length.

(c) White light is made up of seven bands of colors each having different wavelengths. Upon passing through a medium, each of the colors travels at different speeds and hence has different angles of refraction leading to the splitting of the light i.e. dispersion.

Answer 2

Explanation:

a). Dispersion

b). Because white light consists of seven colours namely the VIBGYOR. WHEN it passes through the prism they seperate.

c). Violet
