What is Doppler effect? Find an expression for the apparent frequency heard when the source is in motion and the listener is at rest. What is the limitation of Doppler effect?

What is a simple pendulum? Find an expression for the time period and frequency of a simple pendulum.

What are the frequencies heard when a stretched wire is plucked in the middle ?

A : In Doppler's effect the value of apparent frequency depends on the relative motion between source and observer . R : The change in frequency in Doppler effect is independent from the distance between source and observer .

The frequency of a source of sound as measured by an observer when the source is moving towards him with a speed of 30 m/s is 720 Hz. The apparent frequency when the source is moving away after crossing the observer is x xx 10^2 Hz what is the value of x. ......... (velocity of sound is 330 m/s)

A sound source and listener are both stationary and a strong wind is blowing. Is there a Doppler effect?

Is there a Doppler effect in the case of sound when the observer or the source moves at right angles to the line joining them? How then can we determine the Doppler effect when the motion has a component at right angles to this line?

Is there a Doppler effect in the case of sound when the observer or the source moves at right angles to the line joining them? How then can we determine the Doppler effect when the motion has a component at right angles to this line?

The change in frequency due to Doppler effect does not depend on

What is the effect of temperature and pressure on the frequency of note emitted by an organ pipe ?

(a) What is Dappler effect? The frequency r of a source of sound appears to be n' to a stationary listener when the source is moving with velocity V_s away from him. The velocity of sound is V. Write an expression for n' in terms of r, V and V_s . (b) Distinguish between the characteristics of progressive and stationary waves. Use diagrams to distinguish.
