Two waves of the same amplitude and frequency arrive at a point simultaneously. what should the phase difference between the waves so that amplitude of the resultant wave is double(2A) 

The wavelength of the wave is:

A body executing S.H.M has a maximum acceleration equal to $$48$$ m$$/\sec^2$$ and maximum velocity equal to $$12$$ m/$$\sec$$. The amplitude of S.H.M is?

A nylon guitar string has a linear density of $$7.20\ g/m$$ and is under tension of $$150\ N$$. The fixed supports are distance $$D= 90.0\ cm$$ apart. The string is oscillating in the standing wave pattern shown in figure.Calculate the
(ii) The wavelength of the traveling waves whose superposition gives this standing wave.

A sine wave is travelling in a medium. A particular particle has zero displacement at a certain instant. the particle closest to it having zero displacement is at a distance

A particle performing simple harmonic motion along x-axis, with $$x = 0$$ as the mean position is released from rest at $$x = 2 cm$$ at $$t = 0$$. The time taken by particle in crossing the position $$x = 1.6cm$$ for the second time is: [Take amplitude of simple harmonic motion as $$2cm$$ and its period as $$1s$$]

A particle moves along the X-axis according to the equation $$x = 10{\sin ^3}(\pi t)$$. the amplitudes and frequencies of component SHMs are

A wave of frequency $$100$$ Hz is sent along a string towards a fixed end. When this wave travels back after reflection, a node is formed at a distance of $$10$$ cm from the fixed end of the string. The speeds of incident(and reflected) waves are?

Two periodic waves of amplitudes $$A_{1}$$ and $$A_{2}$$ pass through a region. If $$A_{1} > A_{2}$$, the difference in the maximum and minimum resultant amplitude possible is

The maximum particle velocity is $$8$$ times the wave velocity of a progressive wave. If the amplitude of the particle is $$"a"$$. The phase difference between the two particles seperated by a distance of $$""x"$$ is
