Across
- 3. transfer of wave energy to a material
- 4. bouncing back of waves/object
- 5. EM radiation that can be seen with eye
- 7. wave made of electric and magnetic fields
- 9. wave requires a medium to travel
- 13. disturbance that transfers energy, not matter
- 17. moves medium at right angles (perpendicular)
- 18. bending or spreading of waves around opening
- 19. reflects or absorbs all of the light
- 20. transmits all light without scattering
Down
- 1. scatters light as it passes through
- 2. light reflected at different angles
- 6. energy transferred by EM waves
- 8. complete range of EM waves
- 10. moves medium parallel (same direction)
- 11. distance between two parts of a wave
- 12. max. distance particles move away from rest
- 14. material through which waves travel
- 15. bending of waves due to change of speed
- 16. numbers of waves during amount of time
