What type of EM wave is used for sanitizing equipment?

Back

Ultraviolet (UV) radiation is used for sanitizing equipment.

Front

What do all forms of electromagnetic radiation have in common?

Back

All forms of electromagnetic radiation travel at the same speed in a vacuum, which is the speed of light.

Front

Front

What type of EM radiation is felt as heat on the skin?

Back

Infrared radiation is felt as heat on the skin.

Front

How are different types of light arranged along the electromagnetic spectrum?

Back

Different types of light are arranged by the amount of energy they carry.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (or about 300,000 kilometers per second).

Front

What type of EM radiation can be seen by the human eye?

Back

Visible light is the type of electromagnetic radiation that can be seen by the human eye.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.
