The Foucault experiment provides evidence for the rotation of the Earth. In this experiment, a pendulum is set in motion, and its swing appears to change direction over time. This apparent change in direction is due to the rotation of the Earth beneath the swinging pendulum. As the Earth rotates, the swing plane of the pendulum remains fixed in space, while the Earth moves underneath it. This causes the pendulum`s path to gradually rotate, creating the illusion of a change in direction.

Let`s analyze the options:

Option 1: Revolution of Earth - This option refers to the Earth revolving around the Sun. However, the Foucault experiment does not prove this, as it is specifically designed to demonstrate the rotation of the Earth.

Option 2: Rotation of Earth - This is the correct answer. The Foucault experiment does provide evidence for the rotation of the Earth, as explained above.

Option 3: Rotation of Moon - The Foucault experiment does not provide evidence for the rotation of the Moon. This option can be eliminated.

Option 4: Revolution of Moon - This option refers to the Moon revolving around the Earth. Again, the Foucault experiment does not prove this, so it is incorrect.

Therefore, the correct answer to the question
