So this is where this velocity actually comes from. Now we know what this force of gravity is. It's just G big M little m over r2, that's just Newton's Law of Gravity. And that's equal to mv2 over r. So to figure out what this v2 is, let's go ahead and simplify...
According to Newton’scorpuscular theory, the velocity of light varies with the density of the medium used. This theory also describes three major light phenomena: reflection, refraction, and rectilinear light propagation. The color of light, according to this theory, is also determined by the siz...
