A violin string oscillation in its fundamental mode, generates a sound wave with wavelength `lamda`. To generate a sound wave with wavelength `(lamda)/(2)`. By the string still oscillating is its fundamental mode, tension must be changed by the multiple.

How are the wavelength and frequency of a sound wave related to its speed ?

A string fixed at both ends first oscillates in its fundamental mode then in second harmonic mode.Then match the following.

When a stretched string a length L viberates in its fundamental mode, the sound produced has wavelength =L//2 in air. The velocity of sound in air is V . The velocity of the transverse waves on the string is

What will be the change in the wavelength of a sound wave in air if its frequency is doubled?

A string clamped at both ends vibrates in its fundamental mode. Is there any position (except the ends) on the string which can be touched without disturbing the motion ? What if the string vibrates in its first overtone ?

When a sound wave of wavelength lamda is propagating in a medium, the maximum velocity of the particle is equal to the velocity. The ampilitude of wave is

Length of 0.3 m wire vibrates in fundamental mode at frequency 480 Hz. The velocity of sound wave in air is

A stretched string of length L , fixed at both ends can sustain stationary waves of wavelength lamda Which of the following value of wavelength is not possible ?

(i) A person hums in a wall and finds strong resonance at frequencies 60 Hz, 100Hz and 140 Hz . What is the fundamental frequency of the well? Explain? How deep is the wall ? (velocity of sound = 344 m// ). (ii) A violin string 33cm long vibrates at a fundamental frequency of 440 Hz . Where shold a finger be pressed on the string board so that its decreased length causes it to vibrate in its fundamental mode at five fourth of its original frequnency.
