Two waves having equaitons
`x_1=asin(omegat+phi_1),x=asin(omega+phi_2) `
If in the resultant wave the frequency and amplitude remain equal to those of superimposing waves. Then phase difference between them is

Consider a pair of identical pendulums, which oscillate with equal amplitude independently such that when one pendulum is at its extreme position making angle of 2^@ to the right with the vertical, the other pendulum makes and angle of 1^@ to the left of the vertical. What is the phase difference between the pendulums?

Two points are located at a distance of 10 m and 15 m from the source of oscillation .theperiod of oscillation is 0.05 sec and the velocity of the wave is 300 m s^(-1) .What is the phase difference between the oscillation of two points?

In a plane e.m. wave the electric field oscillates sinusoidally at a frequency of 2 xx10^10 Hz and amplitude 48 Vm^-1 Find wavelength of wave.

What is the ratio of slit widths, when the amplitude of light waves from them have a ratio sqrt2 : 1 ?

The pattern of standing waves formed on a stretched string at two instants of time are shown in the figure.The velocity of two waves superimposing to form stationary waves in 360ms^(-1) and their frequencies are 256 Hz. Calculate the time at which the second curve is plotted.

Two particles of equal masses m and m are connected by a light string of length 2l. A constant force F is applied continuously at the mid-point of the string, always along the perpendicular bisector of the straight line joining the two particles. Show that when the distance between the two particles is x, the acceleration of the particle is a = F/m = (x)/((1^2 - x^2) ^(1//2)

The widths of two slits in an interference experiment ar in the ratio 9:1.What is the ratio of amplitudes and intensitites of light waves from them?

A group between x/m and the presure P of the gas at a constant temperature is called adsorption siotherm. Where x is the no. of moles of the adsorbate and m is the mass of the adsorbent. adsoption isotherms of different shaopes have been experimentally observed .. According to frundlich adosroption isthem, x//m = KP^(1//n) where K and N are constant paraments depending upon the nature of the solid and gas graph between log (x/m) and log P is a straight line a t angle 45^(@) with intercept OA as shown . hence, (x/m) at a pressure of 2 atm is :
