Wave properties II Flashcards
1
Q
What is a superposition?
A
when waves meet, they pass through each other
at the point where they meet, they combine for an instant before they move apart
this combining effect is known as superposition
2
Q
What is the principle of superposition?
A
states that when two waves meet, the total displace at a point is equal to the sum of individual displacements at that point
3
Q
How is a supercrest formed?
A
when two crests meet
the two reinforce eachother
4
Q
What happens when a crest meets a trough of the same amplitude what happens?
A
resultant displacement is zero
the two waves cancel each other out
