  1. Question 1

    Q1. Total internal reflection occurs when light travels from a denser medium to a less dense medium at an angle greater than the:

    • A) Angle of reflection
    • B) Angle of refraction
    • C) Critical angle
    • D) Brewster angle

    Answer: Critical angle

    Explanation: Total internal reflection occurs when light travelling from a denser medium to a less dense medium strikes the boundary at an angle greater than the critical angle, causing all the light to be reflected back into the denser medium with no refraction.
