A sonometer resonates with a source of frequency 500 Hz when the length of the wire between the bridges is 31.5 cm. Now its tension is increased to 4 times. What will be the two possible frequencies of resonance for a length of 21.0 cm?

A sonometer wire resonates with a tuning fork. If the length of the wire between the bridges is made twice even then it can resonate with the same tuning fork. How ?

Frequency of a sonometer wire is n. Now its tension is increased 4 times and its length is doubled then new frequency will be

A sonometer wire is in tnison with a tuning fork of frequency 256 Hz, when the lenghts of the wire between the bridges is 75 cm and only one loop is formed. By keeping the lengths and tension constant, the wire is made to vibrate with 2 loops. The wire can still be in resonance with a tuning fork, provided the freqency of the tuning fork is

A stretched string resonates with a tuning fork of frequency 500 Hz, when the length of the string is 0.75 m. If a tuning fork of frquency 250 Hz is used, then the new resonating length will be

A stretched string resonates with a tuning fork of frequency 480 Hz, when the length of the string is 60 cm. The length of the same string required to vibrate resonantly with a tuning fork of frequency 240 Hz will be

A sonometer wire vibrating in its fundamental mode, is in unison with a tuning fork when the length of the wire between the bridges is 25 cm. By keeping the same tension , the length between the bridges is increased to 75 cm. The tuning fork can still be in resonance with the vibrating wire , provided the wire vibrates with

In a resonance tube experiment, resonance occurs with a tuning fork of frequency 420 Hz, when the length of the air column is 19 cm. Resonance occurs again when the length is increased to 59 cm. When is the velocity of sound in air ?

The length of sonometer wire is doubled and the tension is increases four times. The frequency will

A sonometer wire of length 79 cm emits a note of frequency 234 Hz. The length of the wire is then reduced by 1 cm and is allowed to vibrate. How many beats will be produced per sec with a tuning fork of frequency 240 Hz ?

A sonometer wire of length 100cm has a fundamental frequency of 320 Hz. Then the velocity of the transverse wave is
