Because the wire has to melt when sudden variation in the current/voltage, otherwise it may damage electric instruments inside the house. By melting it avoid a damage to the other instruments hence need to have low melting point fuse wire. (according to H=I^2*R*T ).
The fuse wire is used on the basis on the Joules law of heating.
The law says that when the electric current is allowed to pass trough a conductor, the conductor heats up and is proportional to the square of current.This is because practical conductors have definite resistance(normally it is small).
The heat produced= Isq*R*T
The common material used as fuse wire is an alloy of tin and lead.

The Battle of Verdun is considered the greatest and lengthiest in world history.

Peroscopic is an instrument that used in submarine for seeing the object on water surface, the basic principle used in it that light mechanism, we use two mirror which parelle each other in a tube at 45' angle with two lens for see outside image.
More Details:
A kaleidoscope is a cylinder with mirrors containing loose, colored objects such as beads or pebbles and bits of glass. As the viewer looks into one end, light entering the other creates a colorful pattern, due to the reflection off of the mirrors. Coined in 1817 by Scottish inventor Sir David Brewster.
A periscope (or berinscope) is an instrument for observation from a concealed position. In its simplest form it consists of a outer case with mirrors at each end set parallel to each other at a 45-degree angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles.
A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 1600s (the 17th century) , using glass lenses. They found use in terrestrial applications and astronomy.
A spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum.
The Golden Temple Amritsar India (Sri Harimandir Sahib Amritsar) is not only a central religious place of the Sikhs, but also a symbol of human brotherhood and equality. Everybody, irrespective of cast, creed or race can seek spiritual solace and religious fulfilment without any hindrance. It also represents the distinct identity, glory and heritage of the Sikhs.
