Solution 1

The phenomenon of splitting of white light into its constituent colours is known as dispersion.

Solution 2

Solution 3

3 x 108 m/s is the velocity of electromagnetic radiation.

Solution 4

Light of different colours have different speeds in a medium.
Therefore, the refractive index of glass (the material of prism) is different for different colours of light and the deviation caused by a prism is different for different colours of light.
Violet is deviated the most because in glass, speed of violet is least.
Red is deviated the least because in glass, speed of red is most.

Solution 5

The colour band obtained on a screen on passing white light through a prism is called the spectrum.

Solution 6

Solution 7

(i) It passes parallel with respect to the base of the prism.
(ii) The white light shall split into its constituent colours and a spectrum shall be formed.

Solution 8

Solution 9

The colour band obtained on a screen on passing white light through a prism is called the spectrum.

Solution 10

If a monochromatic light passes through a prism, deviation will occur and not dispersion.

Solution 11

Dispersion occurs because light of different colour bend through different angles while passing through a glass prism.

Solution 12

Solution 13

Solution 14

Solution 15

(i) Roentgen
(ii) Newton
(iii) Hertz
(iv) Marconi
(v) Hershell
(vi) Ritter

Solution 16

In vacuum both the colours have the same speed.
In glass, red colour has a greater speed.

Solution 17
