Newton used his corpuscular theory of light to explain refraction at a boundary between air and a denser medium such as water.
According to Newton's theory, an attractive force acts on the corpuscles perpendicular to the boundary as they enter the denser medium.
Under Newton's model, what happens to the components of the velocity of the corpuscles when they enter the denser medium?
Select one option:
Compare Newton's prediction of the speed of light in a denser medium to Huygens' wave theory prediction, and state the experimental evidence that resolved this debate.
