Two waves, each having a frequency of 100 Hz and a wavelength of 2.0 cm, are travelling in the same direction on a string. What is the phase difference between the waves(a) if the second wave was produced 0.015 s later than the first one at the same place,(b) if the two waves were produced at the same instant but the first one was produced a distance 4.0cm behind the second one ?(c) If each of the waves has an amplitude of 2.0 mm, what would be the amplitudes of the resultantwaves in part (a) and (b)?
