Investigating critical angle and Total Internal Reflection |
Description
|
Two tasks -
Task A is an investigation that determines the refractive index via measurement of the critical angle and the formula 1/n = sin(C). In this task critical angle is found by increasing i until the angle of refraction reaches 90 degrees.
Task B is an investigation that determines the critical angle by finding the point where the intensity of the reflected ray is first 100% of the intensity of the incident ray. |
