A small source of sound vibrating frequency 500 Hz is rotated in a circle of radius `(100)/(pi)` cm at a constant angular speed of `5.0` revolutions per second. The speed of sound in air is `330(m)/(s)`.
Q. For an observer situated at a great distance on a straight line perpendicular to the plane of the circle, through its centre, the apparent frequency of the source will be

A small source of sound vibrating frequency 500 Hz is rotated in a circle of radius (100)/(pi) cm at a constant angular speed of 5.0 revolutions per second. The speed of sound in air is 330(m)/(s) . Q. If the observer moves towards the source with a constant speed of 20(m)/(s) , along the radial line to the centre, the fractional change in the apparent frequency over the frequency that the source will have if considered at reat at the centre will be

A small source of sound vibrating at a frequency 500Hz is rotated along a circle of radius (100)/(pi) cm at a constant angular speed of 5 revolutions per second. The minimum and maximum frequency of the sound observed by a listener situation in the plane of the circle is (speed of sound is 332 ms^(-1) )

A small source of sound vibrating at frequency 500 Hz is rotated in a circle of radius 100//pi cm at a constant angular speed of 5.0 revolutions per second. A listener situates himself in the plane of the circle. Find the minimum and the maximum frequency of the sound observed. Speed of sound in air = 332 m//s .
