A source of sound is travelling at 100/3 m/s along a road
A sound wave of frequency n travels horizontally to the right with speed with speed c. It is reflected from a broad wall moving to the left with speed v. The number of beats heard by a stationary observer to the left of the wall is

a person standing at a point O on a road perpendicular to the track hears a sound of frequency f. The distance of O from A at that time is 4m. If the original frequency is 640Hz ,
A source of sound is travelling at 100/3 m/s along a road ,
then the value of f is (given velocity of sound = 340m/s) ,
towards a point A. When the source is 3m away from A ,
A source of sound is travelling with a velocity of 30 m/s towards a stationary observer. If actual frequency of source is 1000 Hz and the wind is blowing with velocity 20ms in a direction at 60^∘C with the direction of motion of source, then the apparent frequency heard by observer is (speed of sound is 340 m/s)
