For one resonance tube, a tuning fork produces resonance when air column in it has minimum length 50 cm. Now, next length of air column when resonance is produced again is

100 cm

150 cm

200 cm

`66.7` cm

Text Solution

Verified by Experts

The correct Answer is:

Here for a given closed pipe,
`(lamda)/(4) = L _(min) = 50 cm = ` minimum length of resonance tube
(=minimum length of air column)
`therefore` Next possible length of resonance tube,
`(3lamda)/(4) = 3 xx 50 = 150 cm`

In a resonance tube experiment to determine the speed of sound in air, a pipe of diameter 5 cm is used . The column in pipe resonates with a tuning fork of frequency 480 H_(Z) when the minimum length of the air column is 16 cm . Find the speed in air column at room temperature.

In the experiment for the determination of the speed of sound in air using the resonance column method, the length of the air column that resonates in the fundamental mode, with a tuning fork is 0.1m . When this length is changed to 0.35m , the same tuning fork resonates with the first overtone. Calculate the end correction.

A student performed the experiment to measure the speed of sound in air using resonance air-column method. Two resonances in the air-column were obtained by lowering the water level. The resonance with the shorter air-column is the first resonance and that with the longer air-column is the second resonance. Then,

The first resonance length of a resonance tube is 40 cm and the second resonance length is 122 cm . The third resonance length of the tube will be

The internal radius of a 1m long resonance tube is measured as 3.0 cm. A tuning fork of frequency 2000 Hz is used. The first resonating length is measured as 4.5 cm and the second resonating length is measured as 14.0 cm. We shall calculate the following.

If in an experiment for determination of velocity of sound by resonance tube method using a tuning fork of 512 Hz , first resonance was observed at 30.7 cm and second was obtained at 63.2 cm , then maximum possible error in velocity of sound is (consider actual speed of sound in air is 332m//s

A student is performing an experiment using a resonance column and a tuning fork of frequency 244s^(-1) . He is told that the air in the tube has been replaced by another gas (assuming that the air column remains filled with the gas). If the minimum height at which resonance occurs is (0.350+- 0.005)m , the gas in the tube is (Useful information : sqrt(167RT) = 640J^(1//2)mol^(-1//2) , sqrt(140RT) = 590J^(1//2)mol^(-1//2) . The molar masses M in grams are given in the options. take the values of sqrt((10)/(M)) for each gas as given there.)

A column of air at 51^(@) C and a tuning fork produce 4 beats per second when sounded together. As the temperature of the air column is decreased, the number of beats per second tends to decrease and when the temperature is 16^(@) C the two produce 1 beat per second. Find the frequency of the tuning fork.

While measuring the speed of sound by performing a resonance column experiment, a student gets the first resonance condition at a column length of 18 cm during winter. Repeating the same experiment during summer, she measures the column length to be x cm for the second resonance. Then

A sonometer wire is vibrating in resonance with a tuning fork. Keeping the tension applied same, the length of the wire is doubled. Under what conditions would the tuning fork still be is resonance with the wire?
