The water level in the tube is gradually lowered When the water level is 17 cm below the open the open end, maximum intensity of sound is heard. If the room temperature is `20^(@)` C, the speed of sound in air at the temperature is

A tuning fork vibrating with a frequency of 512 Hz is kept close to the open end of a tube filled with water , figure. The water level in the tube is gradually lowerd. When the water level is 17cm below the open end, maximum intensity of sound in heard. If the room temperature is 20^(@)C , calculate (a) speed of sound in air at room temperature. (b) speed of sound in air at 0^(@)C (c) if the water in the tube is replaced with mercury, will there be any difference in your observations?

A tuning fork of frequency 250 Hz is vibrating at one end of a tube as shown in the figure. If maximum sound is heard at the other end, then the velocity of the waves will be

A vibrating tuning fork is held over a water column with one end closed and the other open. As the water level is allowed to fall, a loud sound is heard for water levels separated by 17 cm. If the speed of sound in air is 340 m/s, the frequency of the tuning fork is:

A tuning fork whose natural frequency is 440 H_(Z) is placed just above the open end of a tube that contains water. The water is slowly drained from the tube while the tuning fork remains in place and is kapt vibrating. The sound is found to be echanced when the air column is 60 cm long and when it is 100 cm long . Find the speed of sound in air.

A vibrating tuning fork is held at the mouth of a cylindrical tube in which water is poured gradually. Then for a certain height of water-level in the tube, an intense sound is heard. What is the reason behind it?
