Optics and Waves Flashcards
1
Q
Frequency of a rod fixed at one end?
A
f = n • 1/4l • sqrt(T/u)
2
Q
What are the frequencies of a standing wave?
A
f = n/2l * sqrt(T/u)
3
Q
Amplitude of the reflected, C, and transmitted, B, waves in terms of the amplitude, A, of the incident wave?
A
B = A(2k1/k1+k2) and C = A(k1-k2/k1+k2)
4
Q
What is the wave speed along a string?
A
v= sqrt(T/u) where T is the tension and u is the mass density or v = wavelength x frequency
5
Q
How is wave speed and angular frequency related?
A
w=vk where k is the wave number.
