Across
- 2. a pressure caused by the vibration of something in a medium that transfers energy
- 8. when waves bend around small obstacles or when light bends it when it passes around an edge/slit
- 11. of energy that travel through earth's layers and are a result of natural disasters
- 12. oscillations are perpendicular to the direction of the waves advance
- 16. waves where the disturbance moves in the same direction as the wave, one basic wave
- 17. wave
Down
- 1. of waves that pass a point in
- 3. when waves bend as they pass through a new medium which changes the direction of the waves and can distort images in water
- 4. that are moving keep moving unless a force acts upon it
- 5. surface between the earth's crust and the mantle lying at a depth of about 6-7m under the ocean bed
- 6. that happens repeatedly
- 7. uses sound waves to produce pictures of the inside of the body
- 9. of a wave from equilibrium
- 10. a disturbance in which there is a transfer of energy from place to place
- 13. wave
- 14. a state of balance between opposing forces or actions
- 15. the location of objects by reflected sound
