A stationary source of sound is emitting sound of frequency `500Hz`. Two observers `A` and `B` lying on the same line as the source, observe frequencies `480Hz` and `530 Hz` respectively. The velocity of `A` and `B` respectively are (in `m//s`), speed of sound `=300m//s`.
An observer is moving away from source of sound of frequency 100 Hz. His speed is 33 m/s. If speed of sound is 330 m/s, then the observed frequency is
A source emits a sound of frequency of 400 Hz , but the listener hears it to be 390 Hz . Then
What is your observation when two source are emitting sound with frequency 499 Hz & 501 Hz
A source of sound gives 5 beats when sounded with another source of frequency 100 Hz. The second harmonic of the source together with a source of frequency 200 Hz gives 10 beats s^(-1) . What is the frequency of the source?
A siren emiting sound of frequency 800Hz is going away from a static listence with a speed of 30 m//s frequency of sound to be beand by the listener is ("velocity of sound" = 330 m//s)
An observer moves on the same line on which two sources of sound of frequency 660 Hz are present. The observer observes beat frequency of 10Hz . If speed of sound is 300m//s then speed of the observer is:
