Explain the construction of meter bridge.

A meter bridge has a straight and uniform wire of materials such as Manganin.

The wire is of one-meter length and is stretched along the side of a meter scale AC.
The ends of the wire are attached to thick copper strips of L shape with negligible resistance at A and C.
The L-shaped copper stripes and the wire are mounted on a wooden base horizontally.
Between the two L-shaped copper strips, another thick copper strip D having negligible resistance is fixed in a way that two gaps are formed.

Meter Bridge

In the AD gap, a resistance R is connected whose value is to be measured. In the CD gap, a resistance box S is connected. To complete the Wheatstone bridge, resistances P and Q are formed by dividing the meter bridge wire into parts using a jockey which changes P and Q continuously.

An astronomical telescope consists of two converging lenses. One of them of large aperture and large focal length is called objective lens and the other one, of smaller focal length and smaller aperture is called the eyepiece. It is used to see distant objects which are not seen clearly with naked eyes. The image formed by the objective lens acts as an object for the eyepiece and the final image produced by the eyepiece is magnified.
