Waves Review

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or the spreading of waves when they pass through small openings.

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 energy in electromagnetic waves?

Back

As the wavelength increases, the energy of the electromagnetic wave decreases.

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Front

What is the difference between electromagnetic waves and mechanical waves?

Back

Electromagnetic waves do not require a medium to travel through, while mechanical waves do.

Front

What happens to the pitch of a sound as the source moves toward an observer?

Back

The pitch of the sound increases as the source moves toward the observer.

Front

What happens to the pitch of a sound as the source moves away from an observer?

Back

The pitch of the sound decreases as the source moves away from the observer.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, ordered by wavelength or frequency.

Front

What type of wave is sound?

Back

Sound is a mechanical wave that requires a medium (solid, liquid, or gas) to travel.

Front

What is amplitude in wave terminology?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, related to the energy of the wave.
