y_1 = 8 sin (omegat - kx) and y_2 = 6 sin (omegat + kx) are two waves travelling in a string of area of cross-section s and density rho. These two waves are superimposed to produce a standing wave. (a) Find the energy of the standing wave between two consecutive nodes. (b) Find the total amount of energy crossing through a node per second.

y_1 =4sin( omega t + kx), y2 = -4 cos( omega t + kx), the phase difference is

Three one-dimensional mechanical waves in an elastic medium is given as y_1 = 3A sin (omegat - kx), y_2 = A sin (omegat - kx + pi) and y_3 = 2A sin (omegat + kx) are superimposed with each other. The maximum displacement amplitude of the medium particle would be

Two SHM's are represented by y = a sin (omegat - kx) and y = b cos (omegat - kx) . The phase difference between the two is :

Assertion: Two waves y_1 = A sin (omegat - kx) and y_2 = A cos(omegat-kx) are superimposed, then x=0 becomes a node. Reason: At node net displacement due to waves should be zero.

Which of the following equations can form stationary waves? (i) y= A sin (omegat - kx) (ii) y= A cos (omegat - kx) (iii) y= A sin (omegat + kx) (iv) y= A cos (omegat - kx) .

two waves y_1 = 10sin(omegat - Kx) m and y_2 = 5sin(omegat - Kx + π/3) m are superimposed. the amplitude of resultant wave is

Four simple harmonic vibrations x_(1) = 8s "in" (omegat), x_(2) = 6 sin (omegat +(pi)/(2)) , x_(3) = 4 sin (omegat +pi) and x_(4) =2 sin (omegat +(3pi)/(2)) are superimposed on each other. The resulting amplitude is……units.
