Electromagnetic Spectrum Quiz

An electromagnetic wave forms when a particle that has an electric charge experiences which movement?

• It speeds up.

• It slows down

• It changes direction.

• It makes any of the above motions.

Gamma rays are more harmful than radio waves because

• their energy travels in photons.

• they have a much longer wavelength.

• they travel much faster than radio waves.

• they have a much higher frequency and more energy.

Humans can see light because it

• has a frequency that is higher than other types of radiant energy.

• travels to the eyes faster than other radiant energy.

• has no wavelength.

• has a frequency that human eyes can detect.

Which type of radiant energy is NOT a major component of the energy that reaches Earth from the Sun?

• ultraviolet waves

• infrared waves

• microwaves

• visible light waves

The electromagnetic spectrum is organized according to

• energy, frequency, and wavelength.

• energy, temperature, and wavelength.

• frequency, temperature, and wavelength.

• energy, frequency, and temperature.

The wavelength of a visible light wave is

• longer than a radio wave.

• shorter than an ultraviolet wave.

• longer than a gamma ray.

• the same as a microwave.

A microwave is a low-energy wave that has a

• high frequency and a long wavelength.

• low frequency and a short wavelength.

• high frequency and a short wavelength.

• low frequency and a long wavelength.
