Two sources of sound are separated by a distance 4 m. They both emit sound with the same amplitude and frequency (330 Hz), but they are `180^@` out of phase. At what points between the two sources, will the sound intensity be maximum?

At a place due to beats obtained from two sources of sound

Two sources of sound produce waves differing in wavelength by 12 cm. If the frequencies of the sound are 320 Hz and 360 Hz, calculate the velocity of sound in air.

A source of sound is travelling towards a stationary observer. The frequency of sound heard by the observer is of three times the original frequency. The velocity of sound is v m/s. The speed of source will be

What will happen to interference pattern if two sources of light are not in same phase ?

Waves from two different sources overlap near a particular point. The amplitude and the frequency of the two waves are the same.The ratio of the intensity,when the two waves arrives in the phase to that when they arrive 90^(@) out of phase is

A sounding source has a frequency of 256 Hz. If the temperature of air be 27^@C , what is the wavelength of wavessent by the source? Velocity of sound in air at 0^@C , = 331 m//s .

Two sources of sound A and B produce the wave of 350 Hz ,they vibrate in the same phase.The particle P is vibrating under the influence of these two wave.If the amplitudes at the point P Produced by the two waves is 0.3 mm and 0.4 mm ,then the resultant amplitude of the point P will be [Given AP -BP = 25 cm and the velocity of sound is 350 m/s ]

A train is moving with a uniform speed of 33 m//s and an observer is approaching the train with the same speed. If the train blows a whistle of frequency 1000 Hz and the velocity of sound is 333 m//s then the apparent frequency of the sound that the observer hears is

The lengths of two organ pipes open at both ends are L and L + d . If they are sounde together, then the beat frequency will be
