What are the radiation types in order from lowest to highest energy: microwaves, ultraviolet light, red light, and gamma rays?
The order of energy from least to greatest is: microwaves, infrared, red, ultraviolet, and gamma waves.
The energy of an electromagnetic wave is directly proportional to its frequency. This means that the greater the frequency, the greater the energy. The amount of energy a wave has is determined by using the formula:
As you can see in the diagram below, the order of energy from least to greatest is as given in your list: microwaves, infrared, red, ultraviolet, and gamma waves.
