Sahay Sir > Question Answers > The figure shows a snap photograph of a vibrating string at `t = 0`. The particle `P` is observed moving up with velocity `20sqrt(3) cm//s`. The tangent at `P` makes an angle `60^(@)` with x-axis.
The displacement of the medium in a sound wave is given by the equation y 1 =Acos(ax+bt) where A,a & b are positive constants. The wave is reflected by an obstacle situated at x=0. The intensity of the reflected wave is 0.64 times that if the incident wave. (a) What are the wavelength and frequency of the incident wave ? (b) Write the equation for the reflected wave. (c) In the resultant wave formed after reflection, find the minimum value of the particle speed in the medium?

A source of sound is moving along a circular orbit of radius 3m with an angular velocity of 10 rad/sec. A sound detector located far away from the source is executing S.H.M. along the line with an amplitude 1m. The freuency of oscillation of the detector is 5 per sec. The source is at the point A when the detector is at the point B. If the source emits a continuous sound wave of frequency 340 Hz, the minimum and maximum frequency recorded by the detector (velocity of sound in air = 330 m/s)

A light string is tied at one end to a fixed support and to a heavy string of equal length L at the other end as shown in figure. A block of mass m is tied to the free end of heavy string. Mass per unit length of the strings are mu and 9mu and the tension is T. Find the possible values of frequencies such that junction of two wire point A is a node.
