2. Radio Waves
By #13 and #25

3. Definition
An extremely long electromagnetic wave that is invisible to the unaided eye.
Example displaying how wide of a range radio waves span

4. Frequency Range
10 to the 9th power Hz and lower. They also have wavelengths that measure from tenths of meters to millions of meters.

5. Common Uses Radio stations (AM and FM). Two way radios
Radar (Radio Detection and Ranging)
TV stations
Radio Telescopes

6. Fun Facts
The B-2 spirit has a radar signature the size of one eighth of a mosquito.
Radar guns are used in law enforcement.
Radio telescopes pick up radio signals from space.

Microwaves
By: Allie Unger and Adam Haniff

8. Microwaves DEFINITION
A short electromagnetic wave longer than infrared but shorter than radio waves that is commonly used in cooking and communication.
FREQUENCY
The frequency of a microwave is
3 x 1011 – 3 x 109
Because microwaves reflect off the inside walls of a microwave oven, they may form standing waves. Food lying at the antinodes where the vibrations are at maximum, get cooked more than food lying at the nodes, where there are no vibrations. For that reason, most microwave ovens rotate food items to ensure even heating.

9. Important Information
Microwaves are used in telecommunication and cooking.
Microwaves reflect off of metal.
Without microwaves we would not have microwave ovens.
Microwaves easily transmit through air, glass, paper, and plastic.
The energy used in microwaves can convert into infrared energy.

Infrared light
By Alex Patterson &
Claudia Victoroff

11. Infrared Light
Infrared light is defined as light non visible to the human eye with longer and slower waves than red light.
Frequency- 3*1011Hz<f<3*1014Hz
Wavelength- 1mm>λ>700nm

12. Practical application of infrared light
This type of electromagnetic wave can be useful to the human population by;
Infrared photography- capturing photo with infrared waves. This can show where the thermal energy is in the object shot.
Remote control devices- to communicate messages with the television or other electrical appliance
Weather satellites can track cloud movement with thermal imaging equipment

13. Ultraviolet Light

14. Table Of Contents Definition Frequency range Fun Fact 1 Fun Fact 2

15. Definition
The invisible light that lies above the violet portion of the spectrum and before X-rays.

16. Frequency Range
7.5x1014 Hz<f<5x1015Hz

17. Fun Fact 1
Ultraviolet light is used for sterilizing medical instruments, fruits, and vegetables.

18. Fun Fact 2
Also used for identifying fluorescent materials.

19. Fun Fact 3
Higher energy and shorter wavelength than visible light.

20. Fun Fact 4
9% of sunlight is UV (ultraviolet light). UV light causes sunburn because of its high energy it passes through clouds, causing sunburn even on cloudy days.

21. Visible Light
By:

22. Visible Light Info
The Visible Light Spectrum is all the light that is visible to the unaided human eye.
The frequencies of visible light range from 4.3*1014(Red) to 7.5*1014(Violet).
This shows the separation of visible light from the invisible light.

23. Facts
Without visible light we would not have many important things, including photography (colored), optical telescopes, and optical microscopes. All of which helped us greatly in varying forms of study.
The colors in visible light can change when the light is refracted, because its speed changes.
The visible light spectrum does not include unsaturated colors, which require the constructive or destructive interference of colors.

By: 23 and 17

25. X- Rays
Definition- Waves lower than ultraviolet waves that have a wavelength of 10 to the -8th power. These waves can’t be seen.
Frequency range~ 5* 10 to the 14th power Hz through 3* 10 to the 21st power Hz
Doctors use X-rays to take pictures of bones

26. Important Info. X-rays are not visible (more info.)
X-rays are used as a medical tool (more info.)
X-rays are harmful because they can kill cells, or turn them cancerous (more info.)

27. Not Visible
X-rays are beyond the ultraviolet part of the spectrum, which have higher energy and shorter wavelengths.

28. Medical Purpose
Doctors use X-rays by passing that waves through the body. Most waves go straight through the body but some are absorbed into bones and tissue. The waves that pass through the body show up as waves on the photographic plate. Where there is white is where the bones and tissue are.

29. X-rays Can Be Harmful
When exposed to too many X-rays, it can kill cells in your body, or turn them cancerous.

30. Gamma Rays
Number 6 and 12

31. Definition and Frequency
High energy electromagnetic wave, with high energy photons.
3 x 1018 < f < 3 x 1022 Hz
This is a picture of a Gamma Ray

32. Facts Used for food irradiation, which destroys bacteria in food.
Can kill diseased cancer cells.
Highest electromagnetic wave.
Have highest frequency and shortest wavelength.
Process of food irradiation
