Question

The deflection of light in a gravitational field was predicted first by

• A. Einstein
• B. Newton
• C. Max Planck
• D. Maxwell

Answer 1

The correct option is B Newton

The first observation of light deflection was performed by noting the change in position of stars as they passed near the Sun on the celestial sphere.

This effect leads to the the concept of gravitational lensing.

A gravitational lens refers to a distribution of matter (such as a cluster of galaxies) between a distant source and an observer, that is capable of bending the light from the source, as it travels towards the observer.
