A string fixed at both the ends is vibrating in two segments. The wavelength of the corresponding wave is

A 1 cm long string vibrates with fundamental frequency of 256 Hz. If the length is reduced to 1/4 cm keeping the tension unaltered, the new fundamental frequency will be

The velocity of waves in a string fixed at both ends is 2 m/s. The string forms standing waves with nodes 5.0 cm apart. The frequency of vibration of the string in Hz is

Which of the following is the example of transverse wave?

Two similar sonometer wires given fundamental frequencies of 500 Hz. These have same tensions. By what amount the tension be increased in one wire so that the two wires produce 5 beats/sec?

If the tension of sonometer\'s wire increases four times then the fundamental frequency of the wire will increase by

Four wires of identical length, diameters and of the same material are stretched on a sonometre wire. If the ratio of their tensions is 1 : 4 : 9 : 16 then the ratio of their fundamental frequencies are

A tuning fork vibrating with a sonometer having 20 cm wire produces 5 beats per second. The beat frequency does not change if the length of the wire is changed to 21 cm. The frequency of the tuning fork (in Hertz) must be

If you set up the seventh harmonic on a string fixed at both ends, how many nodes and antinodes are set up in it?

If you set up the ninth harmonic on a string fixed at both ends, its frequency compared to the seventh harmonic
