Question
The drawing shows a graph of two waves traveling to the right at the same speed. (a) Using the data in the drawing, determine the wavelength of each wave. (b) The speed of the waves is 16 m/s; calculate the frequency of each one. (c) What is the maximum speed for a particle attached to each wave?

(b) The speed of the waves is 16 m/s; calculate the frequency of each one. (c) What is the maximum speed for a particle attached to each wave?Explanation / Answer
a) wavelength of A = 2m wavelength of B = 4m b)given velocity v = 16 m/s frequency f = v/wavelength frequency (A) = 16/2 = 8 Hz frequency (B) = 16/4 = 4 Hz c)maximum speed(A) = 2*pi*Amp(A)*f(A) = 2*pi*0.5*8 = 25.132 m/s maximum speed(B) = 2*pi*Amp(B)f(B) = 2*pi*0.25*4 = 6.28 m/s
