A sinusoidal transverse wave moves along a stretched string, Ask an Expert

Academics

a sinusoidal transverse wave moves along a stretched string in the +j direction with amplitude 5 cm, wavelength 2 m, and wave speed 200 m/s. The particles in the string oscillats along the z axis.

a) What are the wave number, frequency, and angular frequency of the wave?

b) Write a possible wave function for the wave with an explanation.

c) If the tension in the string is 50N, what is the linear mass density of the string?

d) How much average power is transmitted along the string?

e) What would the wave function be in (b) if the wave traveled in the -j direction?
