A metallic bar clamped at its middle point vibrates with a frequency v when it is rubbed at one end. If its length is doubled, what will be its natural frequency of vibration ?

The frequency of an open organ pipe is n. If one of its ends is closed then its fundamental frequency will be –

When a body oscillates with its natural frequency then its vibration is called

If the frequency of a wave is doubled, its wavelength

A metallic rod of length 1 m, young's modulus 3xx10^(11)Nm^(-3) and density is clamped at its middle. Longitudinal stationary vibrations are produced in the rod with the total number of displacement nodes equal to 3. The frequency of vibrations is

A string vibrates with a frequency of 200Hz. Its length iss doubled and its tension is altered till it begins to vibrate with a frequency of 300Hz. What is the ratio of new tension to the original tension ?

The fundamental frequency of a closed organ pipe is 'n' . If its length is doubled then frequency will become (neglecting end correction)

The fundamental frequency of an open organ pipe is 512 Hz. What will be its fundamental frequency if its one end is closed ?

A closed organ pipe has a frequency 'n' . If its length is doubled and radius is halved , its frequency nearly becomes .

The frequency of fundamental mode of vibration of a stretched string fixed at both the ends is 25 Hz. If the string is made to vibrate with 7 nodes , what is the frequency of vibration ? If the length of string is 3 m , what is the frequency of the 4th harmonic ?
