Investigating critical angle and Total Internal Reflection



Title 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.
