Front

What is frequency in relation to electromagnetic waves?

Back

Frequency is the number of waves that pass a point in one second, measured in hertz (Hz).

Front

What is wavelength in relation to electromagnetic waves?

Back

Wavelength is the distance between two consecutive peaks of a wave, usually measured in meters.

Front

How are frequency and wavelength related?

Back

They are inversely related; as the wavelength increases, the frequency decreases.

Front

What type of electromagnetic waves can humans see?

Back

Front

What are X-rays used for?

Back

X-rays are used in medical imaging to view the inside of the body.

Front

What are gamma rays?

Back

Gamma rays are high-frequency electromagnetic waves used in cancer treatment and imaging.

Front

What is ultraviolet radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation that comes from the sun and can cause skin damage.
