Answer:

Isaac Newton supported his particle explanation of light by stating that light causes electrons to be emitted from a metal surface.

Explanation: The emission of electrons from metal surfaces when light of sufficient frequency falls on them is known as photoelecteic effect. He discovered photoelectric effect in the 19th century.

His other theories of light like light travels in a straight line could not explain diffraction and reflection. It needed the support of light as a wave to proof it.
