A progressive wave is given by, Y=12 (5 t-4 x) . On this wave, how far away are the two points having a phase difference of 90^ ?

Options

  1. A4
  2. B8
  3. C16
  4. D32

Correct answer

B. 8

Step-by-step solution

Given, y=12 (5 t-4 x) y=12 2 ( 5 t 2 - 4 x 2 ) Comparing above eq. with, y = A 2 ( x - t T ) We get, = 2 4 Relation between phase difference and path difference is aligned & = 2 x 2 & = 2 ( 2 4 ) x x & = 8 aligned
