Across
- 3. wave energy moves back in forth and medium moves up and down
- 5. force forces action on an object that combine a net force that isd bnot zero
- 7. force the combination of all the forces acting on an object
- 9. the bending of a wave around the edges of an opening or an obstacle
- 10. force forces acting on an object that combine and form a net force of zero
- 12. the angle of incidence is equal to the angle of reflection
Down
- 1. the transfer of energy from a wave to a medium
- 2. waves need matter to transfer energy
- 4. waves do not need matter to transfer energy
- 6. the charge in direction of a wave passing from a medium caused by change of speed
- 8. wave wave that matter in medium move forward and backward alone the same direction
- 11. a push or pull onm an object
