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.

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 :

The speed of sound in air and water is 340 m/s and 1420 m/s respectively. If sound waves have a wavelength of 2m in air, then the frequency of the same sound waves in water will be
