Which electromagnetic wave transfers the least amount of energy? gamma X-ray ultraviolet microwave

Answer

option D)

Microwave

Explanation

In the formula

E=ℎv

the v denotes frequency,

the E denotes energy,

the h is Plank's constant

As we can see from the equation that the frequency is proportional to the energy.

So, we can conclude that the electromagnetic wave which have lowest frequency will have the lowest energy.

EM waves Frequency

gamma rays >3*10^17

X-rays 3*10^16 - 3*10^17

ultraviolet light 7,5*10^14 - 3*10^16

visible light 4,3*10^14 - 7,5*10^14

infrared 3*10^12 - 4,3*10^14

microwave 3*10^9 - 3*10^12

Microwave have lowest frequency band, hence it have lowest energy
