A person who is sitting at a distance of 400 m from a source of sound is listening to a sound of 600 Hz. Find the timee period between successive compressions from the source?

A person who is sitting at a distance of 400 m from a source of sound is listening to a sound of 600 Hz. Find the time period between successive compressions from the source? Given : Frequency of sound, n = 600 Hz To find : Time period between successive compressions, T = ?

What would a person hear, if he moves away from a source of sound with the speed of sound?

A source of sound emitting a 1200 Hz note travels along a straight line at a speed of 170 m s^-1 . A detector is placed at a distance of 200 m from the line of motion of the source. (a) Find the frequency of sound received by the detector at the instant when the source gets closest to it. (b) Find the distance between the source and the detector at the instant it detects the frequency 1200 Hz. Velocity of sound in air = 340 m s^-1 .

Two point sources of sound are kept at a separation of 10 cm. They vibrate in phase to produce waves of wavelength 5.0 cm. What would be the phase difference between the two waves arriving at a point 20 cm from one source (a) on the line joining the sources and (b) on the perpendicular bisector of the line joining the sources ?

Two electric trains run at the same speed of 72 km h^-1 along the same track and in the same direction with a separation of 2.4 km between them. The two trains simultaneously sound brief whistles. A person is situated at a perpendicular distance of 500 m from the track and is equidistant from the two trains at the instant of the whistling. If both the whistles were at 500 Hz and the speed of sound in air is 340 m s^-1 , find the frequencies heard by the person.

A photographic plate placed at a distance of 5 cm from a weak point source is exposed for 3 s. If the plate is kept at a distance of 10 cm from the source, the time needed for the same exposure is
