Refraction and Lenses Review

Description: The Refraction and Lenses Review includes 46 questions of varying type. Questions pertain to light refraction, total internal reflection and image formation by lenses. Snell's law is used to analyze the refraction of light at the boundary between two transparent materials. Ray diagrams and the lens equation are used to analyze the object-image relationships for converging and diverging lenses. The following concepts are emphasized: refraction, Snell's law, angle of incidence, angle of refraction, least time principle, boundary behavior, total internal reflection, critical angle, lenses, diverging lenses, converging lenses, focal point, real versus virtual images, inverted versus upright images, lens equation, and magnification equation.

The Review is available in three versions:

  1. Printable Version
    The printable version includes only the questions. There are no answers and no links to online help. It's perfect for printing and using as a practice test.
  2. Questions with Links
    This version includes questions with links to online help that is pertinent to each question.
  3. Finally, you can use the Answers Version of the Review. This inludes questions, answers, explanations/solutions, and links to online help that is pertinent to each question. This version is available with all the questions on one page or with a portion of the questions on one page.
