Question

observation of law of refraction of light​

Answer 1

Law of Refraction. [link] shows how a ray of light changes direction when it passes from one medium to another. As before, the angles are measured relative to a perpendicular to the surface at the point where the light ray crosses it. ... This means that the speed of light is less in medium 2 than in medium 1.
