Sonometer

A tuning fork of frequency 500 Hz produces 8 beats/ second when sounded with a having sonometer wire. What must be the frequency of the sonometer wire, if a slight increases be the frequency of the sonometer wire,if a slight increases in its tension produces fewer beats per second that before ?

A knife-edge divides a sonometer wire into two parts. The fundamental frequencies of the two parts are n_(1) and n_(2) . The fundamental frequency of the sonometer wire when the knife-edge is removed will be

A sonometer wire is under a tension of 40N and the length between the bridges is 60cm. A metre long wire of the sonometer has a mass of 1.0 gm. Deduce the speed of the transverse waves and the frequency of the second harmonic.

A sonometer wire is under a tension of 10 N and the length between the bridges is 2m. A metre long wire of sonometer has mass of 1.0 gm. Deduce the speed of transverse wave and the frequency of 1st hormonic.

A sonometer is set on the floor of a lift. When the lift is at rest, the sonometer wire vibrates with fundamental frequency 256 Hz. When the lift goes up with acceleration a =(9g)/(16) , the frequency of vibration of the same wire changes to

A sonometer wire is divided in many segments using bridges. If fundamental natural frequencies of the segments are n_(1), n_(2), n_(3)….. then the fundamental natural frequency of entire sonometer wire will be (if the divisons were not made):

A sonometer wire under tension of 128 N vibrates in resonance with a tuning fork . The vibrating portion of sonometer wire has length of 20 cm and mass 1 g . The vibrating wire at constant speed of 0.75 m//s and an observer standing near the sonometer hear 1 beat//s . Find the speed of sound in air.

A sonometer wire under tension of 63 N vibrating in its fundamental mode is in resonance with a vibrating tuning fork. The vibrating portion of that sonometer wire has a length of 10 cm and a mass of 1 g. The vibrating tuning fork isnow moved away from the vibrating wire with a constant speed and an observer standing near the sonometer hears one beat per second. Calculate the speed with which the tuning fork is moved if the pseed of sound in air is 300 m/s.

A sonometer wire under tension of 64 N vibrating in its fundamental mode is in resonance with a vibrating tuning fork. The vibrating portion of the sonometer wire has a length of 10 cm and mass of 1 kg. The vibrating tuning fork is now moved away from the vibrating wire with a constant speed and an observer standing near the sonometer hears one beat per second. Calculate the speed with which the tuning fork is moved, if the speed of sound in air is 300 m/s.
