  1. Four Important Properties of Waves

  2. Reflection • Refraction • Diffraction • Interference

  3. 1. Reflection: When a wave hits a reflecting surface, it is reflected outwards at the same angle as it came in.

  4. 1. Reflection Mirror Incident light beam Reflected light beam

  5. 1. Reflection

  6. 2. Refraction: Waves bend when they go from one medium to another (like from air into water or glass)

  7. 2. Refraction

  8. 2. Refraction:

  9. 2. Refraction Different wavelengths bend at different angles, which is what makes a prism able to separate white light into all its colors Refracted Colors Air White Light Glass Prism

  10. 2. Refraction

  11. 2. Refraction Refraction is also what makes lenses work. Light bends when it goes from air to glass. Air Incoming light Focused light Lens

  12. 3. Diffraction Light bends when it goes around around obstacles and through openings

  13. When two waves run into one another, they add if crests overlap, and subtract if troughs overlap 4. Interference

  14. Interference and Diffraction
