Arrange the following types of photons of electromagnetic radiation in order of decreasing energy: red light, radio, x-rays, γ-rays, infrared.

Decreasing order is as follows:

γ-rays > x-rays > red light > infrared > radio

Explanation:

Energy and wavelength are inversely related with each other.

In other words, energy decreases as the wavelength of electromagnetic radiation increases.

Order of wavelength for the given radiations are as follows:

Radio > infrared > red light > x-rays > γ-rays

So, order of the energy will be reverse.

γ-rays > x-rays > red light > infrared > radio

it means there are 3 atoms of oxygen
