A sound signal of 128 vibrations per second has a wavelength of 2.7m. Calculate the speed with which the wave travels.

A sonometer wire under tension of 64 N vibrating in its fundamental mode is in resonance with a vibrating tuning fork. The vibrating portion of the sonometer wire has a length of 10 cm and mass of 1 kg. The vibrating tuning fork is now moved away from the vibrating wire with a constant speed and an observer standing near the sonometer hears one beat per second. Calculate the speed with which the tuning fork is moved, if the speed of sound in air is 300 m/s.

A sonometer wire under tension of 63 N vibrating in its fundamental mode is in resonance with a vibrating tuning fork. The vibrating portion of that sonometer wire has a length of 10 cm and a mass of 1 g. The vibrating tuning fork isnow moved away from the vibrating wire with a constant speed and an observer standing near the sonometer hears one beat per second. Calculate the speed with which the tuning fork is moved if the pseed of sound in air is 300 m/s.

Sound waves from a loudspeaker spread nearly uniformly in all directions if the wavelength of the sound is much larger than the diameter of the loudspeaker. (a) Calculate the frequency for which the wavelength of sound in air is ten times the diameter of the speaker if the diameter is 20 cm. (b) Sound is essentially transmitted in the forward direction if the wavelength is much shorter than the diameter of the speaker. Calculate the frequency at which the wavelength of the sound is one tenth of the diameter of the speaker d- iescribed above. Take the speed of sound to be 340 m s^-1 .

Sound waves produced by two vibrators have the same wavelength in two different gases. The speed of the waves in the two gases are 420 m/s and 400 m/s. The vibrators, when sounded together produce 8 beats/second. The wavelength in the two gases will be

A tuning fork makes 256 vibrations per second in air. When the speed of sound is 330 m//s , the wavelength of the note emitted is :

A tuning fork having frequency 256 Hz emits a wave which has a wavelength of 1.35 m . Find the speed of sound in air.
