...sine ; and the angle KBH is the angle of refraction, whose sine is K I. When the refracting medium is water, the sine of the angle of incidence is to the sine of the angle of refraction as 4 to 3, or as 1.336 to 1 ; which is confirmed by the following experiment, taken from Dr. Smith's Optics.... | |
