Types of EMR

Here are the seven different types of electromagnetic radiation in order from the highest energy to the lowest energy.

• Gamma rays come from nuclear explosions and are very damaging to humans.

• X-rays can also damage humans and cause cancer.

• Ultraviolet is next in line and can cause damage to your skin and eyes.

• Next is visible light which is the only part that our eyes can see.

• Infra-red is what we feel as heat.

• Microwaves have less energy than infra-red. They are used in microwave ovens and give astronomers information about the galaxy.

• Radio waves have the least amount of energy and can penetrate the atmosphere.

EMR can be represented by waves. The waves that have a high frequency are the ones that can do damage to us as they a carry a lot of energy.
