    Identify the correct definition of the critical angle.

    • The critical angle is the angle of incidence when the angle of refraction is exactly 90° and light is refracted along the boundary

    • The critical angle is the angle of refraction when the angle of incidence is exactly 90° and light is refracted along the boundary

    • The critical angle is the angle of incidence when the angle of reflection is exactly 90° and light is reflected along the boundary

    • The critical angle is the angle of incidence when the angle of refraction is exactly 90° and light is reflected along the boundary

                      Why does a prism cause white light to be dispersed?

                      • Light towards the red end of the spectrum slows down less than light towards the violet end of the spectrum as it moves through the glass

                      • Light towards the red end of the spectrum slows down more than light towards the violet end of the spectrum as it moves through the glass

                      • The frequency of the light towards the red end decreases more than the frequency of light towards the violet end of the spectrum

                      • The frequency of the light towards the violet end decreases more than the frequency of light towards the red end of the spectrum
