A source, approaching with speed u towards the open end of a stationary pipe of length L, is emitting a sound of frequency f

_{s}. The farther end of the pipe is closed. The speed of sound in air is v and f_{0}is the fundamental frequency of the pipe. For which of the following combination(s) of u and f_{s}, will the sound reaching the pipe lead to a resonance?2

In an experiment to measure the speed of sound by a resonating air column, a tuning fork of frequency $$500$$ $$Hz$$ is used. The length of the air column is varied by changing the level of water in the resonance tube. Two successive resonances are heard at air columns of length $$50.7$$ $$cm$$ and $$83.9$$ $$cm.$$ Which of the following statements is (are) true?

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 fixed rigid support at $$O.$$ A transverse wave pulse (Pulse 1) of wavelength $${\lambda _0}$$ is produced at point $$O$$ on the rope. The pulse takes time $${T_{OA}}$$ to reach point $$A.$$ If the wave pulse of wavelength $${\lambda _0}$$ is produced at point $$A$$ (Pulse 2) without disturbing the position of $$M$$ it takes time $${T_{AO}}$$ to reach point $$O.$$ which of the following options is/are correct?

Two loudspeakers M and N are located 20m apart and emit sound at frequencies 118 Hz and 121 Hz, respectively. A car in initially at a point P, 1800 m away from the midpoint Q of the line MN and moves towards Q constantly at 60 km/h along the perpendicular bisector of MN. It crosses Q and eventually reaches a point R, 1800 m away from Q.

Let v(t) represent the beat frequency measured by a person sitting in the car at time t. Let v

Let v(t) represent the beat frequency measured by a person sitting in the car at time t. Let v

_{P}, v_{Q}and v_{R}be the beat frequencies measured at locations P, Q and R respectively. The speed of sound in air is 330 ms^{$$-$$1}. Which of the following statement(s) is (are) true regarding the sound heard by the person?Questions Asked from Waves (MCQ (Multiple Correct Answer))
