Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

Which type of electromagnetic wave has the longest wavelength?

Back

Radio Waves have the longest wavelength in the electromagnetic spectrum.

Front

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

Back

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

Front

Which section of the electromagnetic spectrum can humans see?

Back

Humans can see the Visible Light section of the electromagnetic spectrum.

Front

What type of electromagnetic wave has the lowest energy?

Back

Microwaves have the lowest energy among the options provided.

Front

How much of the electromagnetic spectrum is visible to the human eye?

Back

Only a small part of the electromagnetic spectrum is visible to the human eye.

Front

What happens to the energy of an electromagnetic wave as its frequency increases?

Back

The energy of an electromagnetic wave increases as its frequency increases.

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with very high frequency and energy, and they have the shortest wavelength.

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 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.
