COURSE INTRODUCTION & OUTLINE:

Before the beginning of the nineteenth century, light was considered to be a stream of particles.

The particles were either emitted by the object being viewed or emanated from the eyes of the viewer.

Newton was the chief architect of the particle theory of light.

Snell’s law states that a ray of light bends in such a way that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant. Mathematically,

ni sinq i = nr sinqr
