  1. Question 1

    Q1. Total internal reflection occurs when light travels from a denser medium to a rarer medium and the angle of incidence exceeds the:

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

    Answer: Critical angle

    Explanation: Total internal reflection occurs when light traveling from a medium of higher refractive index (denser) to one of lower refractive index (rarer) strikes the interface at an angle of incidence greater than or equal to the critical angle, causing all the light to be reflected back into the.
