Progressive/Stationary Waves Flashcards
1
Q
What is the wavelength of a wave?
A
Distance between any point on a wave to an adjacent one that is exactly in phase with it
2
Q
What is the period of a wave?
A
Time taken for one complete wave to pass a fixed point
3
Q
What is the frequency of a wave?
A
Number of complete waves passing a fixed point per second
4
Q
What is a complete wave?
A
Simply peak to peak; so top to top.
5
Q
How many radians are in a complete wave?
A
2 pi
6
Q
How are stationary waves formed?
A
Two progressive waves with the same frequency and amplitude superposing.
7
Q
What is the distance between two nodes on a stationary wave?
A
Wavelength / 2
8
Q
What is the frequency of the nth harmonic?
A
n x the frequency of the 1st harmonic
9
Q
what does u represent for stationary waves?
A
Mass per unit length of the string
