Waves Review

Front

What is diffraction in the context of waves?

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 frequency in waves?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

Electromagnetic waves travel at the speed of light, approximately 3.00 x 10^8 meters per second.

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

How do sound waves differ from electromagnetic waves?

Back

Sound waves are mechanical waves that require a medium to travel through, while electromagnetic waves do not require a medium.

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 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 is the energy relationship between gamma rays and radio waves?

Back

Gamma rays carry more energy than radio waves.

Front

What is a mechanical wave?

Back

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