A parabolic reflector, dish, or mirror is a device engineers use to collect or project visible light, sound, and radio waves. The bowl shape of the reflector is the three-dimensional surface that can be understood as a parabola revolving around its axis of symmetry.
1. Research one of the applications of parabolic reflectors listed below or do research to find a different application.
Satellite dish, telescope, parabolic microphone, spotlight, car headlight, solar cooker, or PAR can lamp.
2. Explain how your chosen application uses the geometric properties of the parabolic shape to collect or project energy. Be sure to use the terms vertex, focus, and axis of symmetry in your explanation.
3. Include graphs, diagrams, and/or equations in your explanation.
