What is your observation when two source are emitting sound with frequency `499 Hz` & `501 Hz`

What is your observation when two sources are emitting sound with frequency 499 Hz and 501 Hz ?

A source and an observer are situated on two perpendicular tracks as shown in the figure the observer is at rest and source is moving with a speed 50m//s the source emits sound waves of frequency 90Hz which travel in the medium with velocity 200m//s the frequency of sound heard by observer when the source crosses the origin is

A source of frequency X' gives 5 beats/s when sounded with a source of frequency 200 Hz. The second harmonic of source gives 10 beats/s when sounded with a source of frequency 420 Hz. The value of 'x' is

Three sources emitting sound waves of the same amplitude, have frequencies 400 Hz , 401 Hz and 402 Hz , respectively . Find out the number of beats heard per second .

A stationary source emits sound waves of frequency 500 Hz. Two observes moving along a line passing through the source detect sount to be of frequencies 480 Hz and 530 Hz.Their respective speeds are, in ms^(-1) (Given speed of sound =300 m//s )

The frequency of a source of sound as measured by an observer when the source is moving towards him with a speed of 30 m/s is 720 Hz. The apparent frequency when the source is moving away after crossing the observer is x xx 10^2 Hz what is the value of x. ......... (velocity of sound is 330 m/s)

A source frequency f gives 5 beats when sounded with a frequency 200Hz. The second harmonic of same source gives 10 beats when sounded with a source of frequency 420Hz. The value of f is
