Questions and Answers

Which type of incidence occurs when the incident beam strikes the media boundaries at a 90° angle?

  • Acute-angle Incidence
  • Oblique Incidence
  • Obtuse-angle Incidence
  • Perpendicular Incidence (correct)

    • What happens to the transmitted beam in Perpendicular Incidence?

  • It is reflected back
