A particle executes SHM of amplitude A if $$T_1$$ and $$T_2$$ are the time taken by the particle to traverse from 0 to A/2 and from A/2 to A respectively. Then $$T_1/T_2$$ will be equal to 

For a wave propagating in a medium, identify the property that is independent of the others

A uniform rope of length $$L$$ and mass $${m_1}$$ hangs vertically from a rigid support . A block of mass $${m_2}$$ is attached to the free end of the rope. A transverse pulse of wavelength $${\lambda _1}$$ is produced at  the lower end of the rope . the wavelength of the pulse when it reaches the top of the rope is $${\lambda _2}$$. The ratio $$\frac{{{\lambda _1}}}{{{\lambda _2}}}$$ is:

The amplitude of a $$SHM$$ reduces to $$1/3$$ in first $$20$$ second then in first $$40$$ second its amplitude becomes:

A particle of mass $$m$$ oscillates along $$x-$$axis according to equations $$x=a\sin \omega t$$. The nature of the graph between momentum and displacement of the particle is

The graph shown the variation of displacement of a particle executing SHM with time. We inference from this graph that-

Two Waves of amplitudes $${ A }_{ 0 }$$ and $$x{ A }_{ 0 } $$ pass through a region. If x >1, the difference in the maximum and minimum resultant amplitude possible is

 A metal rod 40 cm long is dropped onto a wooden floor and rebounds into air. Compressional waves of many frequencies are thereby set up in the rod. If the speed of compressional waves in the rod is 5500 $$m s ^ { - 1 }$$ what is the - lowest frequency of compressional waves to which the rod resonates as it rebounds?

Consider the wave represented by $$y=\cos(500t-70x)$$ where $$x$$ is in metres and $$t$$ in seconds. the two nearest points in the same phase have a separation of 

A particle is executing simple harmonic motion between extreme positions given by (-1, -2, -3)cm and (1, 2, 1)cm. Its amplitude of oscillation is
