LIght Waves

LIght Waves

By Azizah Mutiarani

​Learning Objectives

1. Define and use the terms normal, angle of incidence and angle of reflection Properly

2. Describe the formation of an optical image by a plane mirror, and give its characteristics, i.e. same size, same distance from mirror correctly

3. ​Describe an experiment to show refraction of light through transparent blocks of different shapes correctly

4. Define refractive index, n, as the ratio of the speeds of a wave in two different regions properly

5. use the equation n= sin i/ sin r correctly

6. use the equation n= 1 / sin c correctly
