What are electromagnetic waves made of?

Back

Electromagnetic waves are made of two waves that are perpendicular to each other: an electric wave and a magnetic wave.

Front

What type of wave are electromagnetic waves?

Back

Electromagnetic waves are transverse waves.

Gamma rays, X-rays, Ultraviolet rays, Visible light, Infrared rays, Microwaves, Radio waves.

Front

What are ultraviolet rays used for?

Back

Ultraviolet rays help the body produce vitamin D, can cause sunburns, and are used to sterilize medical equipment.

Front

What is the photoelectric effect?

Back

The photoelectric effect is when certain wavelengths of the electromagnetic spectrum can strip electrons off metals, which can be seen as sparks.

Front

Which wavelengths of the EMS can cause the photoelectric effect?

Back

Gamma rays, ultraviolet rays, and X-rays can cause the photoelectric effect.

Front

What type of EM wave is used to see inside the body?

Back

X-rays are used to see inside the body and can show breaks in bones.

Front

What is the main characteristic of transverse waves?

Back

In transverse waves, the oscillations are perpendicular to the direction of the wave's travel.

Front

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

Back

As the wavelength increases, the frequency decreases, and vice versa.

Front

What are radio waves used for?

Back

Radio waves are used for communication, including radio and television broadcasts.
