Total internal reflection inside a 45 o glass prism.. The critical angle close critical angle The critical angle is the angle of incidence in the dense medium when the angle of refraction in the ...

When a ray of light that is travelling through a piece of glass strikes the interface between the glass and the air, it changes direction according to Snell’s law. If the angle of incidence is less ...

The angle of incidence above which total internal reflection occurs is called the critical angle and it is a constant for a pair of media. For acrylic glass and air it is 41.8°.
