Optics and Waves

Question 1

Frequency of a rod fixed at one end?

Answer 1

f = n • 1/4l • sqrt(T/u)

Question 2

What are the frequencies of a standing wave?

Answer 2

f = n/2l * sqrt(T/u)

Question 3

Amplitude of the reflected, C, and transmitted, B, waves in terms of the amplitude, A, of the incident wave?

Answer 3

B = A(2k1/k1+k2) and C = A(k1-k2/k1+k2)

Question 4

What is the wave speed along a string?

Answer 4

v= sqrt(T/u) where T is the tension and u is the mass density or v = wavelength x frequency

Question 5

How is wave speed and angular frequency related?

Answer 5

w=vk where k is the wave number.
