Question

4. A transverse traveling wave on a cord is represented by y(x,t) = 0.48 sin (4πx + 10πt)

where y and x are in meters and t in seconds.

a) For this wave determine the wavelength, frequency, phase velocity (magnitude and

direction), amplitude, maximum and minimum transverse speeds of particles of the cord.

b) What is the minimum length of the cord required for a standing wave to be formed when

this wave meets its reflection?

c) Write the equation representing the standing wave. What is the amplitude of vibration for

a particle of the string located at x = 0.15 m?​
