Question

What did isaac Newton believe light was made of

Answer 1

PARTICLE

Step-by-step explanation:

As per the theory proposed by the Newton for the propagation of light he assumed that light is made up of PARTICLEs

He said that light is made up of small rigid particles which behaves elastically. When light shows reflection then this is an example of 100% elastic collision where these particles will strike the surface and rebound with same speed at same angle with the normal

So this theory explains the propagation of light in particle form and hence this theory was known as particle theory of light

So as per Newton's explanation light is made up of PARTICLES

Answer 2

Sir Isaac Newton, held the theory that light was made up of tiny particles. In 1678, Dutch physicist, Christiaan Huygens, believed that light was made up of wavesvibrating up and down perpendicular to the direction of the light travels, and therefore formulated a way of visualising wave propagation.
