When the angle of incidence ________ the critical angle, total internal reflection occurs

The incidence angle of light should be less than critical angle for total internal reflection ?Group of answer choicesTrueFalse

Describe your observations about the relationship between the angle of incidence and angle of reflection.

Total internal reflectionI. Is a phenomenon of refraction of lightII. Occurs when light rays travel into a denser mediumIII. Occurs when the critical angle is just exceededIV.
