Electromagnetism

4. no longer true medium not required
7. All of the frequencies or wavelengths of electromagnetic radiation
8. Electromagnetic waves with wavelengths that are longer than visible light but shorter than microwaves.
9. Electromagnetic waves with the shortest wavelengths and highest frequencies
10. the distance from any point on a wave to an identical point on the next wave
12. Electromagnetic waves with wavelengths that are shorter than visible light but longer than X-rays.
14. all energy that is organized into the electromagnetic spectrum
16. The bending of a wave as it passes at an angle from one medium to another
19. A wave that requires a medium through which to travel
20. A form of energy that can move through the vacuum of space
25. A lens that is thicker in the middle than at the edges
26. The center of interest on a page or set of facing pages, created by using color, contrast and proportion
27. to go in different directions from the same point

1. electromagnetic waves with wavelengths shorter than ultraviolet rays, but longer than gamma rays
2. move further from the nucleus; a higher energy level
3. the number of complete wavelengths that pass a point in a given time
5. A wave in which the vibration of the medium is parallel to the direction the wave travels
6. A lens that is thinner in the center than at the edges
11. mass/volume
13. Electromagnetic waves with the longest wavelengths and lowest frequencies
15. A wave that moves the medium in a direction perpendicular to the direction in which the wave travels
17. the bouncing back of a wave when it hits a surface through which it cannot pass
18. frequency x wavelength
21. radio waves with the shortest wavelengths and highest frequencies
22. to move toward one point
23. Height of a wave
24. when an object causes a wave to change direction and bend around it
