To solve the problem of determining the observed frequency when the observer and source are approaching each other, we will use the Doppler effect formula. The formula varies depending on whether the observer or the source is stationary. ### Given: - True frequency of the source, \( f_0 = 1000 \, \text{Hz} \) - Relative velocity of the observer and source, \( v_{rel} = 50 \, \text{m/s} \) - Speed of sound in air, \( v = 340 \, \text{m/s} \) ### (i) When the Observer is Stationary ...

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 an observer approach each other with same velocity 50 m/s . If the apparent frequency is 435 sec^( –1) , then the real frequency is

A source and an observer approach each other with same velocity 50 m/s. If the apparent frequency is 434 Hz, then the real frequency is (Given velocity of sound = 332 m/s)

At t=0 , observer and source are at same place. Now the source is projected with velocity 60 sqrt2 m/s at 45 ^(@) . Natural frequency of source is 1000 Hz.find the frequency heard by the observer at t=2s. Take speed of sound = 340 m/s

An observer and a source both are moving away with velocity 20 m/s each in opposite direction. If frequency of sound observed is 1800Hz then what is actual frequency (velocity of sound= 340 m/s)

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))

A source and an observer move away from each other with a velocity of 10 m/s with respect to ground. If the observer finds the frequency of sound coming from the source as 1950 Hz , then actual frequency of the source is (velocity of sound in air = 340 m/s )

A source is approaching a stationary observer with uniform acceleration . The frequency of the sound heard by the observer appears to -
