Question

How do you say electromagnetic waves carry energy and momentum?

Answer 1

The energy is determined by the frequency.

EM waves with higher frequencies tend to transfer more energy.

For example, gamma rays transfer high amounts of energy at once due to their high frequency.

This cause them to ionising and very dangerous.

,The lower frequency the less energy transferred at once.

Answer 2

Explanation:

The energy carried by an electromagnetic wave is inversely proportional to its wavelength: E=hλ. The momentum carried by an electromagnetic wave is proportional to its energy: p=Ec
