A source of sound is travelling towards a stationary observer. The frequency of sound heard by the observer is of three times the original frequency. The velocity of sound is v m/s. The speed of source will be

What should be the velocity of earth due to rotation about its own axis so that the weight at equator becomes 2/5 of initial value? Radius of earth on equator is 6400 km and is 10 m/s^2 .

Assertion: The whistle of an approaching engine appears to be shriller than that of a receding engine. Reason: This is due to Doppler effect, which states that if a source of sound approaches the observer, the frequency of sound increases and if the source recedes the observer, the frequency of sound decreases.

A source of sound when moves towards a stationary observer, then frequency of the sound heard by listener is more than actual frequency because the

A source of sound and a listener are both moving in the same direction, the source following the listener. If the respective velocities of sound, source and listener are v, v_s and v_l , then the ratio of the actual frequency of the source and the apparent frequency as received by the listener is

A source of sound and a listener both are moving in the same direction,the source following the listener. If the respective velocities of sound ,source and listener are v, v_s and v_'//s then the ratio of the actual frequency of the source and the apparent frequency as received by the listener is

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 )

If a source of light is moving away from a stationary observer, then the frequency of light wave appears to change because of

A source of sound S is moving with a velocity 50 m//s towards a stationary observer. The observer measures the frequency of the source as 1000 Hz. What will be the apparent frequency of the source when it is moving away from the observer after crossing him? The velocity of sound in the medium is 350 m//s .
