A body is vibrating 7200 times in one minute. If the velocity of sound is 360 m/s, find (i) frequency of the vibration in Hz, (ii) the wavelength of the sound produced.

A .......... is any disturbance that transmits energy without carrying any material with it.

A particle moves on the X-axis is according to the equation $$x = A+B\space \sin\omega t$$. The motion is simple harmonic with amplitude:

Sound travels with a speed of about 330m/s. What is the wavelength of sound whose frequency is 660 Hz?

Which of the following parameters of a wave undergoes a change when wave is reflected from a boundary ?

In a ripple tank, $$10$$ full ripples/s are produced. The distance between peaks of consecutive trough and crest is $$15 cm$$. Calculate the velocity of the ripples.

The maximum displacement of a vibrating body in the medium from its mean position is called _________. Its SI unit is _________.

Two SHMs are represented by $$\displaystyle y=a\sin(w t-kx)$$ and $$\displaystyle y=b\cos (w t -kx)$$. The phase difference between the two is 

When two waves of the same amplitude and frequency but having a phase difference of $$\displaystyle \phi  $$ travelling with the same speed in the same direction (positive x) meets at a point then

Two particles execute S.H.M of same amplitude and frequency along the same straight line from same mean position. They cross one another without collision, when going in opposite direction, each time their displacement is half of their amplitude. The phase-difference between them is
