Question

on the basis of which observation did newton conclude that sunlight is made up of seven colours?​

Answer 1

Answer:

⬇️

He concluded that the different refracted rays of light – well parted from others – could not be changed by further refraction, nor by reflection or other means, except through mixture with other rays. He thus found the seven primary colors red, orange, yellow, green, blue, "a violet-purple" and indigo.
