Given information

Four electromagnetic radiations are given. Those are

a. gamma rays b. radio waves
c. microwaves d. visible light.
These must be listed in order of decreasing energy per photon.

Step-by-step explanation

Step 1.

Planck’s equation states that energy per photon is directly proportional to the frequency as,

 

           

Where,

  • is the energy absorbed by the atom.
  • is the frequency of electromagnetic radiation.
  • is the Planck’s constant.

The energy of electromagnetic radiation is directly proportional to the frequency of the radiation and inversely proportional to the wavelength of the radiation.
