  1. Total Internal Reflection
    Calculate the critical angle of the following materials
    1. Glass with refractive index of 1.54
    2. Ice with refractive index of 1.31
    1. A beam of light is refracted by a type of glass as shown below
      Angle of incidence: 30°
      Angle of refraction: 22°
      Application of Reflected and Refracted Light

      1. Calculate the refractive index of this type of glass.
      2. Calculate the critical angle of the glass.
      1. A ray of light enters a glass prism with a refractive index of 1.50, as shown below;
        Application of Reflected and Refracted Light
        1. Explain what happens as the ray enters the prism
        2. Find the value of angle X
        3. Explains what happens as the ray reaches point O
