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?

Text Solution

Verified by Experts

Frequency `=(1)/("Time period")`
`:.` Time period `(1)/("Frequency")=(1)/(600)`
`T=0.00167` seconds
he time period between successive compressions from the source is 0.00167 seconds.

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.
