A block M hangs vertically at the bottom end of a uniform rope of constant mass per unit length The top end of the rope is attached to a fixed rigid support at 0 A transverse wave pulse Pulse 1 of wavelength X is produced at point O on the rope The pulse takes time TOA to reach point A If the wave pulse of wavelength Ao is produced at point A Pulse 2 without disturbing the position of M it takes time T O to reach point O Which of the following options is are correct Pulse 1 I Pulse 2 AM The time TAO TOA The wavelength of Pulse 1 becomes longer when it reaches point A The velocity of any pulse along the rope is independent of its frequency and wavelength The velocities of the two pulses Pulse 1 and Pulse 2 are the same at the midpoint of rope Solution Answer A C D At any point v F since velocity depends on tension at a point and mass per unit length so time from 0 to A and A to O will be same V TOA TAO Also frequency remain constant at all point To must be same and vis keep it same maximum at O T maximum so must be
