Question

State Foucault’s proof on Earth’s rotation in short.

Answer

Facault's Experiment

Foucault’s pendulum is a device used to demonstrate the rotation of the Earth. When the pendulum swings back and forth, the plane of its swing appears to rotate slowly clockwise or counterclockwise (depending on the location) over the course of a day. This is due to the rotation of the Earth underneath the pendulum. By observing the rotation of the pendulum, Foucault was able to prove that the Earth rotates on its axis.
