A source of sound of frequency `256Hz` is moving rapidly towards wall with a velocity of `5m//sec`. How many beats per second will be heard if sound travels at a speed of `330m//sec`.

A source of sound of frequency 256 Hz moves rapidly towards a wall with a velocity of 5 ms^(-1). How many beats per second will be heard if sound travels at a speed of 330 m/s?

A source of sound of frequency 256 Hz is moving rapidly towards a wall with a velocity of 5 m(s)^-1 .How nmany beats per second will be heard if sound travel at a speed of 330 m(s)^-1 and the observer is behind the source.

A source of sound of frequency 256 Hz is moving towards a wall with a velocity of 5 m/s. How many beats per second will be heard by an observer O standing in such a positoin that the source S is between O and wall? (c=330(m)/(s) )
