Taiwan physics teaching Geometrical Optics and Interference experiment

 Introduction

As we know, optics is very influential in everyday lives i.e., various colorful objects, from the moment we open our eyes in the morning,
will be captured promptly. Maybe that is primarily attributed to different wavelengths of lights, reflected off objects, irradiated into eyes. Base on it, camera works might be carried out and developed. That means light rays from an object will pass through the lens of the camera and get recorded on a film. This experimental kit is designed to familiarize the user with the properties of geometrical optics and physical optics by observing light of different wavelength, reflection, refraction, interference, etc.

Objective

1.Propagation of light.
2.Colors–Additive and subtractive mixing of colors.
3.Mirrors–Determine the focal length of images on concave or convex mirror.
4.Lenses–Determine the focal length of images on concave or convex lens.
5.Prism–Deviation and invertion from refraction.
6.Snell’s Law–Determining the refractive index from rectangular lens or refraction tank.
7.Wave optics–Compare the single slit, double slit and multiple slit, and determine the wave length of laser light source.

Features

1.Easy to use measuring tape on the optical bench will be beneficent to the experimental performance.
2.Magnetic accessories are designed for effective demonstration.
3.Record data on the bench could be easily accessed by varying the position of displaying screen.
4.Laser generator on the micro-scale adjustment will help effective demonstration
