where a plummet line, P, is suspended, is bent or refracted in the It is therefore asserted, with certain exceptions, that a ray | direction BC, or towards the perpendicular; the ray, BC, falling of light in passing from a rare into a denser medium is bent on the looking-glass, L, is reflected at an equal angle through towards the perpendicular, and the contrary when the pencil the water to D; here, on emerging into the air, it is refracted of light emerges from a dense into a rarer medium. It must from the perpendicular or plummet line, L, in the direction DE; be understood that the density or rarity of the body referred hence " the sine of the angle of incidence, divided by the sine of to is not that of specific gravity. Optically considered, one the angle of refraction, is a constant quantity," and is called the body may be denser than another, whilst, physically, it is really index of refraction. The sine is a perpendicular line drawn from lighter ; thus, oil of turpentine is lighter than water, but has a the extremity of an arc to the diameter of a circle. The law of mgher refracting power than the latter, so that a ray of light sines published by Descartes, and known as Descartes' law, was passing from turpentine into water is refracted from the perpen- discovered by Willebrord Snell, a Dutch mathematician, about dicular, and in passing from water into turpentine it is bent 1612. towards the perpendicular.
