Figure shows a tube having sound source at one end and observe at other end. Source produces frequencies upto `10000 Hz`. Speed of sound is `400 m//s`. Find the frequencies at which person hears maximum intensity.

Figure 7.20 shows a tube structure in which signal is sent from one end and is received at the other end . The frequency of the sound source can be varied electronically between 2000 to 5000 Hz . Find the frequencies at which maxima of intensity are detected . The speed of sound in air 340 m//s .

Figure 7.20 shows a tube structure in which signal is sent from one end and is received at the other end . The frequency of the sound source can be varied electronically between 2000 to 5000 Hz . Find the frequencies at which maxima of intensity are detected . The speed of sound in air 340 m//s .

A source of sound has frequency 2000 Hz. If the speed of sound in air 340m//s , find the distance covered by sound when the source completes 400 vibrations.

Figure shows a tube structure in which a sound signal is sent from one end and is received at the other end. The semicircular part has a radius of 10.0 cm. The frequency of the sound source can be varied from 1 to 10 kHz. Find the frequencies at which the ear perceives maximum intensity. The speed of sound in air = 342 m//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

If two sources of frequencies 300 Hz and 303 Hz are sounded simultaneously, time interval between sounds of successive maximum intensity will be

A source of sound is moving towards a high wall with a speed of 20 m/s. The frequency of the sound produced by the source is 400 Hz. If the speed of the sound is 340 m/s, then the beat frequency heard by a person standing near the wall will be

Figure 7.75 shows a tube structure in which a sound signal is bent from one end and is received at the other end . The semicircular part has a radius of 20.0 cm . The frequency of the sound source can be varied electronically between 1000 and 4000 Hz . Find the frequencies at which maxima of intensity are detected. The speed of sound in air = 340 m//s .
