Wave length of two notes in the air are `[ 70/ 153] m` and `[70 / 157] m`. Each of these notes produces 8 beats per second with a tuning fork of fixed frequency . Find the velocity of sound in the air and frequency of the tuning fork.

A sonometer wire produces 2 beats per second with a tuning fork , when the length of the wire is either 102 cm or 104 cm. The frequency of the tuning fork is

Two sound waves have wavelengths 85 / 170 m an 85 /172 m in air. Each wave produces 4 beats /second with a third note of fixed frequency.Find the frequency of the third note.

In a resonance tube the first resonance with a tuning fork occurs at 16 cm and second at 49 cm . If the velocity of sound is 330 m/s , the frequency of tuning fork is

A resonance air column of length 20 cm resonates with a tuning fork of frequency 250 Hz . The speed of sound in air is

What is minimum length of a tube, open at both ends, that resonates with tuning fork of frequency 350 Hz ? [velocity of sound in air = 350 m/s ]

Wavelength of two second waves in air are 80/175 m and 80/ 173 m . Between these waves 8 beats per second are produced . Calculate the velocity of sound in air.

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.

As speed limit is 120 km/h but speed of the car is less than it so that policeman does not punishing the car driver. Two sound notes have wavelengths 83/ 170 m and 83/ 172 m in the air.These noteswhen sounded together produce 8 beats per second.Calculate the velocity of sound in the air and frequencies of the two notes.

A sonometer wire 100 cm long produces a resonance with a tuning fork . When its length is decreased by 10 cm, 8 beats per second are heard. Find the frequency of tuning fork.
