Electromagnetism

3. All of the frequencies or wavelengths of electromagnetic radiation
5. A wave that requires a medium through which to travel
7. electromagnetic waves with wavelengths shorter than ultraviolet rays, but longer than gamma rays
8. the bouncing back of a wave when it hits a surface through which it cannot pass
9. The bending of a wave as it passes at an angle from one medium to another
11. the number of complete wavelengths that pass a point in a given time
13. A lens that is thicker in the middle than at the edges
15. to move toward one point
18. A wave in which the vibration of the medium is parallel to the direction the wave travels
21. when an object causes a wave to change direction and bend around it
22. Electromagnetic waves with the shortest wavelengths and highest frequencies
25. mass/volume
26. A lens that is thinner in the center than at the edges
27. no longer true medium not required

1. Electromagnetic waves with wavelengths that are longer than visible light but shorter than microwaves.
2. radio waves with the shortest wavelengths and highest frequencies
4. Electromagnetic waves with wavelengths that are shorter than visible light but longer than X-rays.
6. move further from the nucleus; a higher energy level
10. to go in different directions from the same point
12. the distance from any point on a wave to an identical point on the next wave
14. all energy that is organized into the electromagnetic spectrum
16. Electromagnetic waves with the longest wavelengths and lowest frequencies
17. The center of interest on a page or set of facing pages, created by using color, contrast and proportion
19. Height of a wave
20. frequency x wavelength
23. A wave that moves the medium in a direction perpendicular to the direction in which the wave travels
24. A form of energy that can move through the vacuum of space
