Module 2 Unit 2 - Superposition of pulses Flashcards
1
Q
What is a super position?
A
When two waves move through the same space , they add algebraically
2
Q
What is an interference?
A
Is when two or more pulses (and waves)interact with each other in the same space and at the same time.
3
Q
Explain the principle of superposition.
A
Where pulses cross,the combined disturbance at any point is equal to the sum of the disturbances.
4
Q
What are the two types of interferences?
A
Constructive and destructive.
5
Q
What is a constructive interference?
A
It’s when two pulses meet,resulting in a bigger pulse.
6
Q
What is a destructive interference?
A
Is when two pulses meet,resulting in a smaller pulse
7
Q
What do constructive interference result in ?
A
Bigger pulse - Reinforcement
8
Q
What do destructive interference result in?
A
Smaller pulse - Concelation
