Question

The given graph (see figure) shows the displacement versus time relation for a disturbance
travelling with velocity of 1500 ms1. If the wavelength of the disturbance is n × 103 m then find n.

Answer 1

The value of n is 750.

Explanation:

Velocity "v" = 1500 m/s

Wavelength "λ" = n x 10^-3  

Time "t" = 5 μ sec = 5 x 10^-6 s

wavelength = Velocity x Time

                   = 1500 x 5 x 10^-6 m

                   = 75 x 10^-4 m

                   = 750 x 0^-3 m

                n = 750

Hence the value of n is 750.

Answer 2

Answer:

Wave length = velocity × time

                      = 1500 * 2 * 10^-6

                      = 3000 * 10^-6

                      = 3 * 10^-3.

n = 3.
