Understanding Superposition of Waves

What happens to the amplitudes of two waves when they are in superposition?

• They multiply together.

• They subtract from each other.

• They add together.

• They remain unchanged.

What is the result of constructive interference between two waves?

• A wave with no amplitude.

• A wave with a larger amplitude.

• Two separate waves.

• A wave with a smaller amplitude.

In destructive interference, what happens to the amplitudes of the waves?

• They remain the same.

• They multiply to form a new wave.

• They cancel each other out.

• They add up to a larger amplitude.

How can superposition be visually represented?

• By numerical data only.

• Through color-coded graphs.

• With simple wave diagrams.

• Using complex waveforms.

What is the amplitude of the superposition of two waves with amplitudes +2 and -2?

• 2

• -4

• 4

• 0

If two waves are phase-shifted by 2π, what type of interference occurs?

• No interference

• Constructive interference

• Partial interference

• Destructive interference

What phase difference leads to perfect destructive interference?

• 360 degrees

• 90 degrees

• 0 degrees

• 180 degrees

What is the result when two waves with equal but opposite amplitudes are superimposed?

• Two separate waves

• A wave with half the amplitude

• A wave with zero amplitude

• A wave with double the amplitude

What does a phase shift of 180 degrees correspond to in terms of wavelength?

• Half a wavelength

• One full wavelength

• No shift

• Quarter of a wavelength

How does a phase shift of 2π affect the position of a wave?

• It does not shift the wave at all.

• It shifts the wave by one full wavelength.

• It shifts the wave by a quarter wavelength.

• It shifts the wave by half a wavelength.
