Two sitar strings A and B are slightly out of tune and produce beats of frequency 5 Hz. When the tension in the string B is slightly increased, the beat frequency is found to reduce to 3 Hz. If the frequency of string A is 427 Hz, the original frequency of string B is

A tuning fork of frequency 510 Hz is vibrated with a sonometer wire and 4 beats per second are heard. The beat frequency increases if the tension in the string is slightly increased. The original frequency of the string is

A tuning fork of frequency 512 Hz is vibrated with sonometer wire and 6 beats per seconds are heard. The beat frequency reduces if the tension in the string is slightly increased. The original frequency of vibration of the string is

A tunning fork is frequency 512Hz is vibrated with a sonometer wire and 6 beats per second as heard The beat frequency reduces if the tension in the string of slightly increased. The original frequency of vibration of the string is

A tuning fork vibrating with sonometer, having tension in the wire as T , Produces 4 beats per sec. The beat frequency does not change when tension in the wire changes to 1.21 T . Find the frequency of the tuning fork (assuming that the sonometer wire is vibrating in the same mode in both cases )

A tuning fork of frequency 200 Hz is in unison with a sonometer wire . Tension is the wire of sonometer is increased by 1% without any change in its length . Find the number of beats heard in 9 s.

State two ways by which the frequency of a note given out by a stretched vibrating string can be increased.

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is

How is the frequency of a stretched string related to: Its tension?

The fundatmental frequency of a sonometer wire increases by 6 Hz if its tension is increased by 44% keeping the length constant. Find the change in the fundamental frequency of the sonometer when the length of the wire is increased by 20% keeping the original tension in the wire.
