Question

EXPLAIN THE WORKING OF SEISMOGRAPH .​

Answer 1

WORKING OF SEISMOGRAPH :-

• Seismograph instruments are placed on the surface of the earth so, whenever the ground starts shaking the instrument's case moves.

• There is a seismometer inside the seismograph so, only seismograph instruments case moves while seismometer remains still without any movement.

• Seismograph instruments have a large powerful magnetic system for detection and case is wrapped with numerous coils of wire.

• When an earthquake happens the case moves in relative the magnet move and generates an electric signals to the wire which further sent to the computer to create a seismogram.

Answer 2

Answer:

A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage.
