Solve this: A travelling wave in a string is represented by y = 3 sin π 2 t π 4 x . The phase difference between two particles separated by a distance 4cm is (take x and y in cm and t in seconds ) ( 1 ) π 2 r a d ( 2 ) π 4 r a d ( 3 ) π r a d ( 4 ) 0 Share with your friends Share 22 Anshu Agrawal answered this Dear student, The equation of the string is given byy=Asin(kx-ωt)Phase difference ∆φ=2πλ∆xFrom the equation k=2πλ=π4so Phase difference ∆φ=π4×4(given in the question)Phase difference ∆φ=π rad Option 3 is correct.
