Unformatted text preview: PHY134 OPTICS Exp. 8 Abstract In this lab, we will demonstrate the principles of reflection and refraction. 1 Knowledge and Understanding Goals At the end of this lab, your should understand all the following: • Snell’s law of refraction. • What is the meaning of the “critical angle” for total internal reflection. • How the “ray box” makes rays appear on the paper. • How to use the lens equation 1 d o + 1 d i = 1 f . • How to use the magnification equation m =- d i d o . 2 Equipment • Ray box, white light source, • 1 mirror, 1 protractor, 1 glass prism • Optical bench • 3 converging lenses, 1diverging lens • 2 lens holders • Ground glass screen with holder,. The main piece of apparatus for this lab is the so-called “Ray Box”. The ray box is shown in Figure 1. This device uses a slotted mask to block a white light source making a series of visible rays on a piece of paper. Optical elements (lenses, mirrors, ...) can be placed on the paper to reflect or refract the light.paper....
