NEET Physics Waves Sonometer MCQs

In a sonometer experiment, the fundamental frequency of a wire of length 'l' is 'f'. If the length is reduced to 'l/2', keeping the tension constant, the new fundamental frequency will be:

A sonometer wire resonates with a tuning fork. If the tension in the wire is increased by four times, the length of the wire should be _______ to maintain resonance with the same tuning fork.

Which of the following factors does NOT affect the fundamental frequency of a sonometer wire?

The fundamental frequency of a sonometer wire is 200 Hz. If the tension is kept constant and the length is doubled, the new fundamental frequency will be:

A sonometer wire is in unison with a tuning fork of frequency 300 Hz. If the tension in the wire is increased, the length of the wire must be ______ to bring it back into unison with the tuning fork.

In a sonometer, the bridges are used to:

A sonometer wire of length 1 m is vibrating in fundamental mode with a frequency of 100 Hz. If the length is reduced to 0.5 m, keeping tension constant, the new fundamental frequency will be:

Two sonometer wires of the same material and cross-section are under tensions in the ratio 1:4. If their lengths are in the ratio 4:1, the ratio of their fundamental frequencies will be:

In a sonometer experiment, the fundamental frequency of a wire is found to be 200 Hz. If the tension in the wire is increased by four times and the length is halved, the new fundamental frequency will be:

A sonometer wire under a tension resonates with a tuning fork of frequency 480 Hz. When the length of the wire is increased by 10 cm, it resonates with the same fork when the tension is increased by 20%. What is the original length of the wire?
