In stationary wave.

In Melde’s experiment in the transverse mode, the frequency of the tuning fork and the frequency of the waves in the strings are in the ratio.

Two wires are producing fundamental notes of the same frequency. Change in which of the following factors of one wire will not produce beats between them.

A1 cm long string vibrates with fundamental frequency of 256 Hz. If the length is reduced to1/4 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

A stretched string of length I, fixed at both ends can sustain stationary waves of wavelength λ, given by

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

A string on a musical instrument is 50 cm long and its fundamental frequency is 270 Hz. If the desired frequency of 1000 Hz is to be produced, the required length of the string is

A string of 7 m length has a mass of 0.035 kg. If tension in the string is 60.5 N, then speed of a wave on the string is

If the length of a stretched string is shortened by 40% and the tension is increased by 44%, then the ratio of the final and initial fundamental frequencies is
