A wave is moving along a string. The equation giving the displacement y of a point at coordinate x and
at time t has the form y = 0.2cos(4pi(x)/5-20pi(t))where the units are in meters and seconds.
i.)Calculate the frequency and the speed(m/s) of the wave.
ii.)By reflecting this wave from rigid support, standing transverse waves are set up on a stretched string. It is observed that the string is vibrating in its SECOND HARMONIC. Calculate the length of this string in meters.
