1.	Instantaneous profile of a rope carrying a progressive wave moving from left to right is shown, Find the correct option:
Answer» Both P and Q are moving UPWARDS Both P and Q are moving downwards P is moving upwards and Q is moving downwards P is moving downwards and Q is moving upwards Solution :`V_p=-`(WAVE speed)(slope) Slope at `P` is positive, `V_p` at `P` is NEGATIVE Slope at `Q` is negative `V_P` at `Q` is positive. So, `P` is moving downwards and `Q` is moving upwards.
