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. Mark nodes and antinodes on the curve.

A body is vibrating 6000 times in one miute. If the velocity of sound in air is 360 ms^-1 . Find wavelength of the wave produced.

Find the wavelength of electromagnetic waves of frequency 6 xx 10^(12)Hz in free space. Give its two applications.

A wire stretched between two rigid supports vibrates in itsfundamental mode with a frequency of 45 Hz. The mass of the wire is 3.5 xx 10^-2 kg and itslinear mass density is 4.0 xx 10^-2 kg m^-1 . What is the tension in the string?

Two stones are thrown up simultaneously from the edge of a cliff 200 m high with initial speeds of 15 m s^-1 and 30 m s^-1 . Verify that the graph shown in Fig. 3.27 correctly represents the time variation of the relative position of the second stone with respect to the first. Neglect air resistance and assume that the stones do not rebound after hitting the ground. Take g = 10 m s^-2 . Give the equations for the linear and curved parts of the plot.
