Across
- 4. This is constant for all electromagnetic waves
- 5. Light travels faster than sound, true or false?
- 6. What type of wave are sound waves
- 8. What type of wave are light waves (and all other electromagnetic waves)
Down
- 1. The number of waves that pass a single point per second
- 2. Distance between the same points on two consecutive waves in a diagram
- 3. The time taken for a whole wave to completely pass a single point
- 7. This is calculated by multiplying frequency by wavelength
- 9. Distance from equilibrium to maximum displacement (crest or trough) on a diagram
