Question

State whether the following statement is true or false:

The speed of light in a vacuum is $1.24\times {10}^8{\text{ms}}^{-1}$.

• A. True
• B. False

Answer 1

The correct option is B False

Light:

1. It is also defined as radiation that makes visible to the human eye.
2. Light is an electromagnetic wave transverse in nature and does not need any medium to travel. Light travels in vacuum or air with the speed of $3\times {10}^8{\text{ms}}^{-1}$.
3. The speed of light in diamond is $1.24\times {10}^8{\text{ms}}^{-1}$.

So, the given statement is false.
