Which type of electromagnetic radiation has the highest frequency?
Likurg_2 [28]

Explanation:

As we know that relation between energy and wavelength is as follows.

                  E = \frac{hc}{\lambda}

This means that energy is inversely proportional to wavelength. So, more is the energy of an electromagnetic radiation less will be its wavelength.

Also,          f = \frac{c}{\lambda}

Hence, less will be the wavelength more will frequency of a radiation.

Gamma rays are the rays that have highest energy, small wavelength and highest frequency.

Thus, we can conclude that gamma rays are the electromagnetic radiation which has the highest frequency.
