Question

Note: Use principles of physics to solve the problem and then verify your answer using the simulation.

(a) In the simulation above, set the amplitude to 0.420 m, the frequency to 2.00 Hz, and the string thickness to 4.00 cm. Under these conditions what is the speed of the wave on the string? Note that for each of the slider settings in the simulation exactly an integer number of half-wavelengths fit in the 1.00 meter length of the string. Use that information to find the wavelength rather than relying on the wavelength displayed by the simulation, which shows only two decimal places.
____________ m/s

Explanation / Answer

Here,    the speed of the wave on the string   =   wavelength * frequency

=>    the speed of the wave on the string   =   (2 * L/n) * frequency

                                                                     =    (2 * 1/1) * 2.00

                                                                     =    4 m/sec
