When source of sound moves towards a stationary observer, the wavelength of sound received by him

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

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 .

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 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 police car travels towards a stationary observer at a speed of 15 m//s . The siren on the car emits a sound of frequency 250 Hz. Calculate the recorded frequency. The speed of sound is 340 m//s .

When the light source is moving towards an observer,

An observer starts moving with uniform acceleration ‘a’ towards a stationary sound source emitting a whistle of frequency ‘n\ As the observer approaches source, the apparent frequency heard by the observer varies with time as
