TOPIC: WAVE MOTION

1.      At a time t = 0, a train of waves has the form. The velocity of the wave is 30cm/s. Find the equation giving the waveform at a time t = 2s.

2.      What is the amplitude, the wavelength and the velocity of the wave represented by the formula. Where x, is the distance and t is the time.

3.      A simple harmonic wave of amplitude 8units transverses in line of particles in the direction of +X-axis. At any given instant of time, for a particle at a distance of 10cm from the origin, the displacement is 6units and for a particles at a distance of 25cm from the origin the displacement is 4units. Calculate the wavelenght.
