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

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

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.
