Question

Part A What is the frequency of this wave? Part A What is the frequency of this wave? Part B What is the wavelength of this wave? Part C What is the speed of this wave? Please show all work. Part B What is the wavelength of this wave? Part C What is the speed of this wave? Part C What is the speed of this wave? Please show all work. The displacement of a wave traveling in the positive x x-direction is y(x,t) =(3.5 cm) cos(2.7x-92t), where x is in m and t is in s.xm What is the frequency of this wave? What is the frequency of this wave? What is the wavelength of this wave? What is the speed of this wave?

Explanation / Answer

A) we can see that w = 92

thus f = 92/(2*pi)=14.6 Hz

b) we can see that k = 2.7 = 2 pi/lambda

lambda = 2*pi/2.7=2.33

c) v = lambda f = 2.33*14.6=34 m/s
