Wave - Superposition Review

Front

What is superposition in wave theory?

Back

Superposition is the principle that when two or more waves overlap, the resultant wave is the sum of the individual waves.

Front

What does it mean for waves to be in-phase?

Back

Waves are in-phase when their crests and troughs align, resulting in constructive interference.

Front

What does it mean for waves to be out-of-phase?

Back

Waves are out-of-phase when the crest of one wave aligns with the trough of another, resulting in destructive interference.

Front

What happens to the amplitude of waves that are in-phase?

Back

The amplitude of the resultant wave is greater than the amplitude of the individual waves.

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 does redshift indicate about a galaxy's movement?

Back

Redshift indicates that a galaxy is moving away from us.

Front

What does blueshift indicate about a galaxy's movement?

Back

Blueshift indicates that a galaxy is moving toward us.

Front

How do you calculate the frequency of a wave?

Back

Frequency (f) is calculated by dividing the wave speed (v) by the wavelength (λ): f = v/λ.

Front

What is the wave speed of a wave?

Back

Wave speed is the speed at which a wave travels through a medium.

Front

What is a standing wave?

Back

A standing wave is a wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.
