Light: Reflection and Refraction

Syllabus: Content Areas and Learning Objectives

Introduction to Light
Reflection of Light
  • State the laws of reflection of light, in order to understand how light travels in a medium when it encounters another object.
Spherical Mirrors
  • Outline the rule of image formation by spherical mirrors in order to complete the ray diagrams by drawing reflected rays.
  • Represent the path of incident ray and reflected ray in order to decipher the position and nature of image formed.
Mirror Formula & Magnification
  • Express u, v, f in the mirror formula in order to apply sign convention in solving word problems to find the unknown variable.
  • Deduce the nature and size of image by magnification in order to relate height of object with height of image.
Refraction of Light

Demonstrate the path of light when it travels through a rectangular glass slab, in order to formulate laws of refraction of light.

Refractive Index

Compare speed of light in one medium with another in order to calculate refractive index.

Refraction by Spherical Lenses, Image Formation
  • Represent the path of incident & reflected light rays from a concave lens, in order to decipher the position and nature of image formed.
  • Illustrate the path of incident & reflected light rays from a convex lens, in order to decipher the position and nature of image formed.
Lens Formula and Magnification
  • Construct the lens formula for a lens relating v, u, f; in order to find an unknown variable given the other two.
  • State the magnification for a lens, in order to relate height of object with height of image.
Power of a Lens

Calculate the power of a lens, in order to determine its power to converge or diverge.
