Question:

A wave with a wavelength of 0.184 m and an amplitude of 0.136 cm is set up in a rope with a linear density of 169 g/m and kept under a tension of 65.3 N. The wave travels to the right.

Part 1)

What is the velocity of the wave?

v= m/s

Part 2)

Assuming that at t=0, x=0 and y=0, write an equation to describe this wave.

y(x,t)= sin() cm

Part 3)

A second identical wave with a phase of ϕ=0.122 rad behind the first wave is also set up in the rope. Write an equation to describe the rope now.

y(x,t)= sin() cm
