A driver in a stationary car blows a horn which produces monochromatic sound waves of freqeuncy 1000 Hz normally towards a reflecting wall. The wall approaches the car with a speed of `3.3(m)/(s)`.

A driver in a stationary car horns which produces monochromatic sound waves of frequency n=1000Hz , normally towards a reflecting wall. If the wall approaches the car will a velocity u=3.3(m)/(s) , calculate the frequency of sound reflected from wall and heard by the driver. What is the percentage change of sound frequency of reflection from the wall?

A driver in a stationary car horns which produces sound waves having frequency 2000 Hz. The waves are directed normally towards a reflecting wall. If the wall approaches the car with a velocity u = 3.3 m/s. The change in the frequency of sound after reflection from the wall is x%. Then x

Bus moving with speed v forwards a stationary wall. it produces sound of frequency f = 420 Hz. The heard frequency of reflected sound from wall by driver is 490 Hz . Calculate the speed v of bus. The velocity of sound in air is 330 m/s .

Bus moving with speed v forwards a stationary wall. it produces sound of frequency f = 420 Hz. The heard frequency of reflected sound from wall by driver is 490 Hz . Calculate the speed v of bus. The velocity of sound in air is 330 m/s .

A car blowing a horn of frequency 350 Hz is moving normally towards a wall a speed of 5 m/s The beat frequency heard by a person standing between the car and wall is (speed of sound in air =350 m/s )
