The figure shows four progressive waves A, B, C, and D with their phases expressed with respect to the wave A. It can be concluded from the figure that

The diagram below shows the propagation of a wave. Which points are in same phase?

Figure here shows an incident pulse P reflected from a rigid support. Which one of A, B, C, D represents the reflected pulse correctly?

Which of the following curves represents correctly the oscillation given by y = y₀ sin (ωt – ɸ), where 0 < ɸ < 90?

The correct graph between the frequency n and square root of density (ρ) of a wire, keeping its length, radius and tension constant, is

A sound source emits sound waves in a uniform medium. If energy density is E and maximum speed of the particles of the medium is v_max .The plot between E and v_max is best represented by

If the speed of the wave shown in the figure is 330m/s in the given medium, then the equation of the wave propagating in the positive x-direction will be (all quantities are in M.K.S. units)

Two pulses travel in mutually opposite directions in a string with a speed of 2.5 cm/s as shown in the figure. Initially the pulses are 10 cm apart. What will be the state of the string after two seconds?

Two tuning forks P and Q are vibrated together. The number of beats produced are represented by the straight line OA in the following graph. After loading Q with wax again these are vibrated together and the beats produced are represented by the line OB. If the frequency of P is 341Hz, the frequency of Q will be
