Question

Which of the following lists electromagnetic radiations from lowest to highest energy?

Your answer:
radio waves, microwaves, ultraviolet radiation, visible light
microwaves, radio waves, visible light, X-rays
radio waves, infrared radiation, visible light, ultraviolet radiation
gamma radiation, infrared radiation, visible light, X-rays

Answer 1

Highest wavelength : radio waves

So lowest energy: radio waves

Hence order is:

radio waves < microwaves < IR waves < visible light < ultraviolet radiation < X-rays < gamma rays
