VIBGYOR indicates different colours of visible light , i.e. Violet, Indigo, Blue , Green, Yellow, Orange , Red .
 
Light is part of electromagnetic spectrum .
 
Electromagnetic spetrum consists of x-rays, ultra-violet rays, visible light, infrared waves , microwaves and radio waves .
 
All of the above memebers of electromagnetic spectrum are commonly called as electromagnetic waves .
 
All electromagnetic waves travel in vacuum or air with speed 3 × 108 m/s.
 
Frequency and wavelength of individual memeber will vary

(a) Choose the correct statement with respect to Refraction of light [1] 1. The colour always changes when light enters from one optical medium to another. 2. Absorption of light when it strikes the surface of a medium is refraction. 3. Speed of light changes when it enters from one optical medium to another of different optical density. 4. Speed of light does not change when it enters from one optical medium to another of different optical density.
