Curve 'y-x' at an instant for a wave travelling along x-axis on a string is shown. Slope at the point A on the curve, as shown, is 53°.

Select all that apply

• Option A

  Transverse velocity of the particle at point A is positive if the wave is travelling along positive x-axis.

• Option B

  Transverse velocity of the particle at point A is positive if the wave is travelling along negative x-axis of the particle at point A

• Option C

  Magnitude of transverse velocity of the particle at point A is greater than wave speed.

• Option D

  Magnitude of transverse velocity of the particle at point A is lesser than wave speed.
