# Phase different and Intensity?

1)Determine the phase difference between the waves.

How to find it?

2)The intensity of wave Y at point P is I.

Determine, in terms of I, the intensity of wave Z

Thanks

1) Both waves displace along the t-axis, which is x=0

So one way to find the phase difference will be to find the difference in t-axis when the waves cross over to positiveY-wave crosses over at 0 ms, while Z wave crosses over at 1.0 msso phase difference = 1.0 ms - 0 ms = 1.0 ms2) Intensity of Y-wave = 4μm = I Intensity of Z-wave = 2 μm = ½I
