# What are the radiation types in order from lowest to highest energy: microwaves, ultraviolet light, red light, and gamma rays?

Dec 7, 2017

The order of energy from least to greatest is: microwaves, infrared, red, ultraviolet, and gamma waves.

#### Explanation:

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:

$E = h \nu$,

where:

$E$ is energy in Joules, $h$ is Planck's constant, and $\nu$ (pronounced noo) is frequency in $\text{Hz}$.

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.
