What is sin I in Snell's law?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
In Snell's law, "sin i" (or sin I) represents the sine of the angle of incidence—the angle at which light strikes the interface between two media, measured from the perpendicular (normal) to the surface. This is a crucial component because it determines how much the light will bend when entering a new medium.
