What is the only part of the electromagnetic spectrum that is visible to the human eye?

Back

Visible Light is the only part of the electromagnetic spectrum that can be seen by the human eye.

Front

What happens to frequency as wavelength decreases?

Back

As wavelength decreases, frequency increases.

Front

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

Back

Waves with longer wavelengths have lower energy, while waves with shorter wavelengths have higher energy.

Front

What are microwaves used for?

Back

Microwaves are used for cooking food, in communication technologies, and in radar.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, often associated with heat.

Front

What are X-rays used for?

Back

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

Front

What is ultraviolet radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation with wavelengths shorter than visible light, known for its ability to cause sunburn.
