Question

Speed of light in air is_________$m/s$.

Answer 1

1. Light is a form of energy that enables us to see the objects around us.
2. Light is an electromagnetic wave.
3. Light does not require any material medium for its propagation.
4. Speed of light in air or vacuum is i.e$3\times {10}^8$$m/s$.
5. Speed of light changes while going from one medium to another medium.

Hence, the speed of light in air is $3\times {10}^8$ $m/s$.
