List the types of electromagnetic radiation in order of in­creasing energy per

Solution 33P

Step 1:

The photon energy is the energy carried by a single photon with a certain electromagnetic wavelength and frequency. The higher the photon's frequency, the higher its energy. Equally, the longer the photon's wavelength, the lower its energy.

It is calculated using the formula :

E = or E = hf

        Where, E = energy per photon

                 h = planck’s constant = 6.626 10-34 J /s

                 c = speed of light = 3108 m /s

                = wavelength of light

                 f = frequency of light.
