A wire of length 'l' is vibrating in three segments. What is the wavelength of the note emitted?

The fundamental frequeney of a sonumeter wire of length 'l' is f_(0) A bridge is now introduced at a distance of Deltal from the centre of the wire (Deltal lt lt l) . Find the number of beats heard if both sides of the bridge are set into vibration in their fundamental modes.

A line segment of length 2l sliding with ends on the axes, then the locus of the middle point of the line segment is

A tuning fork of frequency 250Hz produces 4 beats per second with a wire of length 25cm vibrating in its fundamental mode. The beat frequency decreases when the length is slightly shortened. What could be the minimum length by which the wire be shortened so that it produces no beats with the tuning fork?

A open pipe of length l is vibrating in 3rd overtone with maximum amplitude A. The amplitude at a distance of (l)/(16) from any open end is

A streched wire vibrating in fundamental mode is in unision with a tuning fork. Keeping the same tension, the length of the wire between the bridges is doubled. The tuning fork can still be in resonance with the wire. Provided the wire now vibrates in

One end of a horizontal thick copper wire of length 2L and radius 2R is welded to an end of another horizontal thin copper wire of length L and radius R. When the arrangement is stretched by applying forces at two ends, the ratio of the elongation in the thin wire to that in the thick wire is

A wire of length l is cut into two parts which are bent respectively in the form of a Square and a circle. What are the lengths of pieces of wire so that the sum of areas is least?
