Since the critical angle is the incident angle that will give total internal reflection. 
This í90 degreesí that occurs when light is at the critical angle never occurs, but it 
is automatically reflected. My teacher told me this is because light canít be in two 
mediums at once, and Ď90 degreesí at a media boundary is being at two mediums 
at once. What exactly is happening when light tries to be in two mediums?
