Clarifications: Each clarification provides an explanation of an indicator/objective to help teachers better understand the skills and/or concepts.

Standard 5.0 Physics

Topic D. Wave Interactions

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

Objective b. Based on observations trace the path of a ray of light before and after it is reflected (bounces) off a plane mirror.

Clarification
Light is a form of energy. Light travels in straight lines or rays. Light spreads out from a source in all directions. Light can reflect or bounce from a surface. If light strikes a plane mirror at an angle, it will reflect at an equal and opposite angle from the mirror.
