Interference - Superposition

Question 1

What is interference between two waves

Answer 1

Interference defines the result of two waves that are travelling at the same time.

Question 2

What is called being out of phase?

Answer 2

Being out of phase is when one source of wave is 0.5 3/2, 5/2, wavelengths out from each other. Being out of phase also means that

Question 3

What does being out of phase cause?

Answer 3

Being out of phase causes destructive interference. As being 1/2, 3/2, 5/2 wavelengths apart from each other means the crest of one wave overlaps with the trough of the other wave, causing the oscillations to cancel out.

Question 4

What is being in phase?

Answer 4

Being in phase, means that two or more wavelengths with the same amplitude, and frequency are travelling at the same time, meaning that the crests and troughs of the wave add together

Question 5

What is constructive interference

Answer 5

Constructive interference is when the crests of two waves add together or the troughs of two waves add together, resulting in a larger amplitude of oscillation.

Question 6

What is destructive interference?

Answer 6

Destructive interference is when two waves overlap, however the crest of one wave lays on top of the trough of another wave. This means that the crest and trough cancel out and result in no oscillation

Question 7

What is superposition?

Answer 7

Superposition is the remaining oscillation pattern of two waves that overlap each other
