A progressive wave is represented by y=10sin(1000πt-πx\34)
Two layers of the wave separated by 153cm have a phase difference of?

can you draw the waveforms in a graphing calculator or similar?

basically you have to work out the periodicity, period or inverse= wavelength of the wave, (lambda) then it (the answer) will often be lambda/2 or over 4 or some related multiple of 1.53 metres

typical {phase difference} answers would be 45 degrees, 90 degrees, 135 degrees or π/2, π/3 etc as you can only get a maximum of 360 degrees of phase difference, then it is back in phase!
