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 glass tube of length 1m is filled with water . The water can be drained out slowly at the bottom of the tube . If a vibrating tuning fork of frequency 250Hz is brought at the upper end of the tube and the velocity of sound is 330 m/s , then the total number of resonance obtained will be

A tuning fork of frequency 440 Hz is to be mounted on a wooden box with one end open to reinforce its sound. What would be the length of the sounding box ? (Velocity of sound in air = 332 ms^(-1) )

A tuning fork of frequency 340Hz is vibrated above a cylindrical hallow tube closed at one end . Poured in it. What is the maximum height of water required for resonance ?

A tuning fork has frequency 512 Hz. The number of vibrations of the fork in the time during which the sound from the tuning fork reaches 332 m in air are (velocity of sound in air is 332 m//s .)

A tuning fork of frequency 440 Hz resonates with a tube closed at one end of length 1.8 cm and diameter 5 cm in fundamental mode. The velocity of sound in air is

A tuning fork of frequency 440 Hz resonates with a tube closed at one end of length 18 cm and diameter 5 cm in fundamental mode. The velocity of sound in air is

A tuning fork of frequency 90 Hz is sounded and moved towards an observer with a speed equal to one - tenth the speed of sound. The note heard by the observer will have a frequency

A tuning fork vibrating with a frequency of 500 Hz is kept close to the open end of a tube filled with water, as shown in figure. 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 500 Hz is kept close to the open end of a tube filled with water, as shown in figure. The water level in the tube is gradually lowered When the water level is 17 cm below the open to 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
