Indicator 3. Provide evidence to show that light travels in a straight line until it is reflected or refracted.

Objective a. Observe and describe the images formed by a plane mirror.

  • Size of the image
  • Apparent distance of the image from the mirror
  • Front-to-back reversal in the image.

Clarification

Light can reflect or bounce from a surface. Mirrors are flat pieces of glass with a silver backing that reflect light. Objects reflected in a plane (flat) mirror are reversed front to back, but are the same size and distance away as the original object.
