Doppler shift in frequency does not depend upon:
Correct answer: B. The distance of the source from the listener
- A. The actual frequency of the wave
- B. The distance of the source from the listener
- C. The velocity of the source
- D. The velocity of the observer
Explanation
Doppler formula depends on velocities and original frequency but not on separation distance; intensity falls with distance, but frequency shift is independent of distance.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.

Doppler's effect is not applicable for:
A tube closed at one end and containing air produces, when excited, the fundamental note of frequency 512 Hz. If the tube is open at both ends, the fundamental frequency that can be excited is (Hz).
Progressive waves of frequency 300 Hz are superimposed to produce a system of stationary waves in which adjacent nodes are 1.5 m apart. What is the speed of the progressive waves?
An observer standing at the sea coast observes 54 waves reaching the coast per minute. If the wavelength of the waves is 10 m, find the velocity.
A whistle giving out 450 Hz approaches a stationary observer at a speed of 33 m/s. The frequency heard by the observer in Hz is (speed of sound = 330 m/s).
If velocity of sound in a gas is 360 m/s and the distance between a compression and the nearest rarefaction is 1 m, then the frequency of sound is:
