A source and an observer are approaching one another with the relative velocity `40 ms^(-1)`. If the true source frequency is 1200 Hz, deduce the observed frequency under the following conditions:
(i) All velocity is in the source alone.
(ii) All velocity is in the observer alone.
The source moves in air at `100 ms^(-1)` towards the observer, but the observer also moves with the velocity `v_(0)` in the same direction.

A source and observer are approaching one another with the relative velocity 40ms^(-1) . If the true source frequency is 1200 Hz, deduce the observed frequency under the following conditions: (i) All velocity is in the source alone. (ii) All velocity is in the observer alone. (iii) The source moves in air at 100ms^(-1) towards the observer, but the observed also moves with the velocity v_(0) in the same direction. (Velocity of sound 340 m/s)

A source and an observer are approaching one another with the relative velocity 40m/s. If the true source frequency is 1200Hz, find the observed frequency under the following conditions : (I)All velocity is in the source alone (ii) All velocity is in the observer alone

A source and an observer is approaching closer with a relative velocity of 40 ms^(-1) . If the true frequency of the source is 1200 Hz calculate the observed frequency under these conditions: (i) the source alone is moving (ii) the observer alone is moving. Take velocity of sound in air to be 340 ms^(-1) .

An observer and source are approaching one another with a relative velocity of 50 m/s. If the true frequency of the source is 1000 Hz, determine the observed frequency when (i) Observer is stationary (ii) Source is stationary

A source of sound is moving away from an observer at rest with a velocity of 50 m s^(-1) . If the frequency of sound is 200 Hz , find the apparent frequency observed by the observer. (Take velocity of sound = 300 m s^(-1))

An observer is approaching a stationary source with a velocity 1/4 th of the velocity of sound. Then the ratio of the apparent frequency to actual frequency of source is
