Answer:
Decreasing order is as follows:
γ-rays > x-rays > red light > infrared > radio
Step-by-step 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
