The wavelength of two waves are 50 and 51 cm respectively. The temperature of the room is 20^(@)C . What will be the number of beats produced per second by these waves, if the speed of sound at 0^(@)C is 332 m/sec?

Wavelengths of two sound waves in air are 81/174 m and 81/175 m. When these waves meet at a point simultaneously, they produce 4 beats per second. Calculate the velocity of sound in air.

Two sound waves with wavelengths 5.0 cm and 5.5 cm, respectively each propagate in a gas with velocity 330 m/s. The number of beats per second will be …………

The wavelengths of two sound waves in air are 81 /173 m and 81 /170 m . They produce 10 beats per second. Calculate the velocity of sound in air.

At normal temperature and pressure the velocity of sound in air is 330 m/s . If the temperature increased to 30^@C and the pressure remains the same the velocity of sound in air will be
