PPT-Light and Optics Notes

By Kristine Optical devices An optical device is any technology that uses light An optical device can be as simple as a mirror or as complex as the Hubble Space Telescope Microscopes Hans and Zacharias Jansen of the Netherlands first built a microscope in about 1595.

A . wave. is a disturbance that transfers energy from one point to another without transferring matter. . Eg. . Water waves.. Prepared for HICIAO CDR. Author: Vern Stahlberger.

The "ray" in geometric optics is an abstraction or "instrument", that can be used to predict the path of light.. Up to now we have been studying . geometric optics. . Today we will look at effects related to the . wave nature of light –. . physical optics. polarization. interference. thin film interference. Measurements of the speed of light (c) .

Light is retransmitted from or “bounces off” an object. Optics. Law of Reflection:. The angle of incidence equals the angle of reflection.. Optics. Refraction. Light “bends” or changes its angle as it moves from one medium to another.. It wasn’t until the early 19. th. century that light was theorized to behave as something other than a stream of particles.. Isaac Newton proposed the particle theory of light.. Newton’s theory was used to explain the reflection and refraction of light.. Light travels in a STRAIGHT LINE . ANOTHER WAY TO THINK OF LIGHT. Light leaving the candle travels in all directions, but we only SEE the light that travels in to our Eye-Brain. ANOTHER WAY TO THINK OF . they are: Geometrical optics - this area of optics operates on the primary assumption that light travels in a straight line.
