Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

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

How does frequency relate to energy in electromagnetic waves?

Back

As the frequency of electromagnetic waves increases, the energy of the waves also increases.

Front

What happens to wavelength as frequency increases?

Back

As frequency increases, the wavelength decreases.

Front

What type of electromagnetic radiation has the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

What type of electromagnetic radiation has the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

Front

What is ultraviolet radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays.

Front

Why is ultraviolet radiation considered hazardous?

Back

Ultraviolet radiation can cause skin damage and increase the risk of skin cancer due to its high energy.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What are microwaves used for?

Back

Microwaves are commonly used for cooking food and in communication technologies.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

Electromagnetic waves travel at the speed of light in a vacuum, approximately 299,792 kilometers per second.
