Assertion : A rainbow is a natural spectrum appearing in the sky after a rain shower.
Reason : It is caused by reflection of sunlight by tiny water droplets present in the atmosphere.
- Both assertion and reason are correct and reason is the correct explanation.
Rainbow is an arc shaped natural dispersion of light seen in the sky after rain.
This is mainly due to total internal reflection of the light waves from the water droplets leading to dispersion and splitting of white sunlight into its component colours.
The sunlight enters the droplets by refraction. From the back surface , they undergo Total Internal Reflection and emerge out the droplet to form the colour spectrum.
