A particle is executing S.H.M. its potential energy v/s displacement graph is given by

The value of restoring force constant is :-

A heavy rope is suspended from rigid support. A wave pulse is set up at the lower end. Then

If the distance between successive compressions and rarefaction in a sound wave is 2 m and velocity of sound is 360 m/s, then the frequency is

The following figure depicts snapshot of a wave travelling in a medium. Which pair of particles are in phase?

In a transverse progressive wave of amplitude A, the maximum particle velocity is four times its wave velocity. The wavelength of the wave is:-

Equation of a standing wave is expressed as y = 2Asinωt coskx. In this equation, quantity w/k represents.

The displacement wave in a string is given as y = 5sin(62.8x – 157t). Here y and x are in cm and t in second. The wavelength of the wave is

A stretched wire vibrates with a frequency of $80Hz$ when the tension is $T_1$ and frequency of $150Hz$ when the tension is $T_2$ . When the tension is $\left(T_1+T_2\right)$ , its frequency of vibration is (in Hz)

A source of frequency $\text{'}X\text{'}$ gives 5 beats/s when sounded with a source of frequency $95Hz$ . The third harmonic of source $\left(X\right)$ gives 10 beats/s when sound with a source of frequency $290Hz$ . The value of $X$ is

The equation of a wave traveling on a string is y = 10sin $\left[\pi \left(5t-\frac{x}{4}\right)\right],$  where x, y are in cm and t is in second. The velocity of wave is
