Across
- 3. A wave consisting of oscillating electric and magnetic fields that can travel through empty space without a physical medium
- 5. A space that contains absolutely no matter, meaning mechanical waves like sound cannot travel through it
- 10. The entire range of all types of electromagnetic radiation, ordered by wavelength, frequency, and energy
- 11. The bending of a wave as it passes from one medium to another because the speed of the wave changes
- 12. The number of waves that pass a fixed point in one second, measured in Hertz (Hz)
- 13. The maximum displacement from the equilibrium (rest) position, which is directly related to the energy of the wave
- 15. The distance between two consecutive identical points on a wave, such as from one crest to the next
Down
- 1. A wave that requires a medium (matter) to vibrate through, such as a sound wave or water wave
- 2. A wave where the medium moves back and forth in the same direction the wave travels, also known as a compression wave
- 4. The transfer of energy from a wave to the medium through which it is passing
- 6. A disturbance that transfers energy through space or a medium without transferring matter
- 7. The standard unit of measurement for frequency, representing one wave cycle per second
- 8. A wave in which the medium moves at right angles (up and down) to the direction the wave travels
- 9. The substance—such as a solid, liquid, or gas—through which a wave travels
- 14. The change in direction or bouncing back of a wave when it strikes a surface
