You can use this tool for light ray passes from a one medium to another to find the critical angle. If you know one angle and one side length of a right traingle, you can find all the other values. The light initially enters the glass hemi cylinder perpendicularly (at right angles) to the glass (point a) and because of this, no bending of the light occurs.
If the angle of incidence were exactly critical, then the angle of refraction would be a right angle. What is the physics behind it. If you know one angle and one side length of a right traingle, you can find all the other values. Shows how rays change direction when they strike mirrors and pass through lenses. Include a ray diagram to explain the concept.
