Across
- 1. The number of complete waves that pass a given point in a certain amount of time
- 4. High-energy electromagnetic waves emitted from a nucleus as it changes from an excited state to a ground energy state
- 5. A physical environment in which phenomena occur
- 7. The speed at which a wave travels
- 9. Radio waves with the shortest wavelengths and the highest frequencies
- 10. A wave that can travel only through matter
- 14. Occurs when an object cause a wave to change direction and bend around it
- 15. The distance from any point on a wave to an identical point on the next wave
- 16. The location within a design that attracts the most attention; the center of interest. In a corsage, the focal point is where the largest flower is placed.
- 20. To vary; go in different direction from the same point
- 21. All of the frequencies or wavelengths of electromagnetic radiation
- 23. Electromagnetic waves with wavelengths that are longer than visible light but shorter than microwaves.
- 25. A lens that is thinner in the center than at the edges
- 26. The transport of dissolved substances into cells
- 27. A wave vibrating in the direction of propagation.
Down
- 2. A form of energy that can move through the vacuum of space
- 3. Electromagnetic waves with the longest wavelengths and lowest frequencies
- 6. The bending of a wave as it passes at an angle from one medium to another
- 8. A type of energy that comes to Earth from the Sun, can damage skin and cause cancer, and is mostly absorbed by the ozone layer
- 11. A lens that is thicker in the center than at the edges
- 12. Lit
- 13. A wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
- 17. A transformation that "flips" a figure over a mirror or reflection line.
- 18. Mass/Volume
- 19. Height of a wave
- 22. Electromagnetic waves with wavelengths shorter than ultraviolet rays, but longer than gamma rays
- 24. To move toward one point, approach nearer together
