Question

laws of refraction of light​

Answer 1

1)normal,refracted ray and the incident ray lie on the same plane

2)sin i /sin r =n i.e refractive index (refractive index is the bending ability of light rays)

Answer 2

The law of refraction, which is generally known as Snell's law governs the behave of light rays as they propagate across a sharp interface between two transparent dielectric media. ... the incident ray, the refracted ray and the normal to the interface of two media at the point of incidence all lie in the same plane.
