What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is a continuous range of frequencies for electromagnetic radiation.

Front

What type of electromagnetic waves can you see?

Back

Visible light.

Front

Which has a higher frequency: visible light or ultraviolet rays?

Back

Ultraviolet rays have a higher frequency than visible light.

Front

What is the relationship between wavelength and frequency?

Back

The longer the wavelength, the frequency is less.

Front

Do X-rays and gamma rays have higher frequencies than ultraviolet rays?

Back

True.

Front

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation with longer wavelengths and lower frequencies.

Front

What are X-rays used for?

Back
