Standing Waves Flashcards
1
Q
How do they happen?
A
Result from the superposition of two opposite waves which are otherwise identical
2
Q
Is energy transferred by standing waves?
A
No
3
Q
How is a wave reflected after hitting a wall?
A
A wave hits a wall and is reflected identically opposite
4
Q
What is the formula for distance between adjacent anti nodes?
A
λ/2
5
Q
Formula for one closed end and one open end:
A
λ = 4L/n
6
Q
Formula for two closed ends:
A
λ = 2L/n
7
Q
Formula for two open ends:
A
λ = 2L/n
8
Q
What is λ?
A
λ (Lambda) indicates wavelength of any wave
9
Q
What is L?
A
L = length
10
Q
What is n?
A
N is the mode
If n=2 we would say the string is vibrating in the second harmonic, and if n=3 then third harmonic
