Question

Problems A standing wave s setup c 1 a string at the third harmonic (n-3), as seen in the figure. The length of the s ring is l 0.350 m, the tension in the string is 2.44 N and the mass per unit lengti is 0.100 kg/m. (5 Points) a) What is the wavelength i nd frequency fof the standing wave? (5 points) /b) If the amplitude of the v ave is 0.0750 m, write the displacement as a function of position x and time t, i e., D(x, ). (5 Points) c) How many nodes are th ere and what are the x positions of all of the nodes (including end points) in the system? Take x 0 to be the position of the left boundary (5 Points) d) How many antinodes a e there and what are the x positions of all of the antinodes in the system? Takex 0 to be the position of the left boundary. (SPoints)Ve) If the tension in the strin; was doubled, what would the fifth harmonic(mt)sha 、 frequency be?

can someone please help with b,c,d,e. Please show all work.
