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​

Respuesta :

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 .
