Electromagnetic radiations:
What are the common features among all the Electromagnetic radiations?
Ans: 1. They all can be described in terms of oscillating electric and magnetic fields perpendicular to each other.
2. They are transverse in nature.
3. All the radiations travel with the speed of light
