Across
- 4. occurs when a wave strikes an object or surface and bounces off
- 5. bending of a wave as it moves from one medium to another medium
- 6. bending of waves around a barrier
- 8. when the crest of a wave overlaps the trough of another wave
- 9. waves that can travel through matter or space; include radio waves, infrared waves, visible light waves, ultraviolet waves, X rays and gamma rays
- 11. a type of mechanical wave in which the wave energy causes matter in the medium to move up and down or back and forth at right angles to the direction the wave travels
- 14. a type of wave that can travel only though matter
Down
- 1. a type of mechanical wave in which matter in the medium moves forward and backward along the direction the wave travels
- 2. when the waves meet, the crest of one wave overlaps the crest of another wave
- 3. occurs when two of more waves combine and form a new wave when they overlap
- 7. number of wavelengths that pass a given point in one second; measured in hertz(Hz)
- 10. for a transverse wave, one half the distance between a crest and a trough
- 12. for a transverse wave, the distance between the tops of two adjacent crests or the bottom of two adjacent troughs; for a compressional wave, the distance from the centers of adjacent rarefactions or adjacent compressions
- 13. rhythmic disturbance that carries energy but not matter
