Cambridge Lower Secondary PhysicsStage 8 Light and sound Checklist

Learning objectives

• 8Ps.01I can describe reflection at a plane surface, and use the law of reflection.
• 8Ps.02I can describe the refraction of light at the boundary between air and glass, or between air and water, in terms of a change of speed.
• 8Ps.03I know that white light is made of many colours, and that this can be shown by using a prism to disperse white light.
• 8Ps.04I can describe how colours of light can be added, subtracted, absorbed and reflected.
