Question

State whether the following statement is True or False.

Velocity of infrared radiations is \(3 \times 10^{8} \mathrm{~ms}^{-1}\).

Answer 1

This statement is true.

Explanation:

• Infrared radiations are electromagnetic waves.
• All electromagnetic waves travel with the same speed of 3 × 10⁸ m/s in vacuum (or air).
• Hence, the velocity of infrared radiations is 3 × 10⁸ m/s.
