Interference and Superposition

Question 1

when a wave hits a soild object what does it do?

Answer 1

Reflects

Question 2

Constructive interference

Answer 2

is when two waves add their amplitudes together when they meet.

Question 3

Destructive interference

Answer 3

is when two waves cancel or reduce each other’s amplitude when they meet.

Question 4

Principle of Superposition

Answer 4

When two waves meet, we can determine the resulting amplitude during the meeting using the Principle of Superposition which states:

“When two waves interfere, the resulting displacement of  the medium at any location is the algebraic sum of the  displacements of the individual waves at that same location.”
