Transcript of Isaac Newton - Nature of Light

Optics A little history... Isaac Newton and the nature of light. The earliest scientific theories of the Nature of light took place around the end of the 17th century.
Sir Isaac Newton, after discovering the visible spectrum said that light is composed of tiny particles, or corpuscles emitted by luminous bodies. Light Wave Theory Light can be both a wave theory, and a particle theory at the same time, but most of the time they act like a wave. Light waves can also be called electromagnetic waves because they are made up of both electric (E) and magnetic (H) fields. Electromagnetic fields swing vertical to the direction of wave travel, and vertical to each other. Light waves are known as transverse waves as they swing in the direction along the direction of wave travel. The study of the behavior of light is called optics.

It covers the reflection of light by either a mirror or an object. example: a prism or lens causes refraction of the light and deflection. If Light hits an opaque object, it causes diffraction of the light.
