The 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

Which type of electromagnetic radiation has the highest frequency?

Back

Gamma Rays.

Front

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

Back

A wave with a long wavelength has a low frequency and low energy, while a wave with a short wavelength has a high frequency and high energy.

What is the primary use of X-rays in medicine?

Back

X-rays are primarily used for imaging to view the inside of the body, such as bones and teeth.

Front

How does the frequency of a wave relate to its energy?

Back

Higher frequency waves carry more energy than lower frequency waves.
