Question 27

Waves

The above figure shows the motion of a progressive wave along a string. The particle motion of the medium is in the direction

Diagram for this question
  1. A.parallel to OX.
  2. B.Parallel to OY
  3. C.60° to OX.
  4. D.60° to OY.
Show the answer and explanation

Answer: B (Parallel to OY)
