Question

The vibrations of a string fixed at both ends are represented by y=16sin(πx/15 )cos(96πt). Where x and y are in cm and t in seconds. Then the phase difference between the points at x=13cm and x=16 in radian​

    Answer:

    Explanation:

    y = 16 sinπx/15 cos(96πt)

    When t = 0

    y = 16 sinπx/15

    here πx/15 is phase of the point at x

    if x = 13

    Phase = 13π/15

    if x = 16

    Phase = 16π/15

    Phase difference

    = 16π/15 – 13π/15

    = 3π/15

    = π/5 radian .
