First 173 words of the document:

The Electromagnetic Spectrum.
Speed of everything in electromagnetic
spectrum 300,000,000ms-1
Black objects Absorb light waves.
Radio Waves:-
1mm <wavelength< Kilometre
Used for radio, TV, mobile phones
Frequency 104 ­ 108 Hz
Wavelength..... 10-2m
Shorter wavelength, easily absorbed by water
This is why they are used for microwave ovens
When water absorbs microwaves, energy of waves is converted to heat
Frequency 108 ­ 1010 Hz
Infra Red:-
Very short wavelength... 10-5m
Can be detected by infra red film
Frequency 1010- 1013 Hz
Visible Light:-
Wavelength.... 0.5x10-6m
Red Orange Yellow Green Blue Indigo Violet
Where red has the longest wavelength, nearest to infra red, and violet has the
shortest wavelength, nearest to Ultra Violet
Frequency 1013 - 1016
Ultra Violet:-
Wavelength.... 10-8m
Very high energy and short wavelengths
Honey bees can see UV
Frequency 1016 ­ 1017Hz

Here's a taster:

Wavelength.... 10-10m
So much energy and short wavelength that they can go through flesh
Have trouble getting through bones and lead due to more calcium metal in
bones. Used for xray.
Frequency 1017 ­ 1019Hz
Gamma Ray:-
Wavelength.... 10-12m
Nasty!, very high energy, will even go through metals, can be used to find
cracks in metals.…read more
