Fireworks
FIREWORKS MAY CONTAIN ALUMINUM, IRON, STEEL, ZINC OR MAGNESIUM DUST IN ORDER TO CREATE BRIGHT, SHIMMERING SPARKS. THE METAL FLAKES HEAT UP UNTIL THEY ARE INCANDESCENT AND SHINE BRIGHTLY OR, AT A HIGH ENOUGH TEMPERATURE, ACTUALLY BURN. A VARIETY OF CHEMICALS CAN BE ADDED TO CREATE DIFFERENT COLORS.
Frequencies of Light
wavelength measured in nm = nanometer
Spectroscope
Spectroscope
Hydrogen and Helium
We know that the sun is made of hydrogen and helium because we see these spectra when we use a spectroscope.
Electricity is used to excite electrons.
Hydrogen
Bright red, bright blue, some purple, no orange, green or yellow
Helium
A lot of gapsNo orange or greenBright yellow and red
Nitrogen
No blue or purple A lot of red Large gaps in the

Oxygen
A lot of blue and green, no yellow or orange; bright blue and green lines

“Man, you got your 1310, your 1490 and the 1550,”refers to wavelengths of different lights carrying information. 1310 nm is used for data you are sending out to the world, such as photos or your voice on the telephone. 1490 is the wavelength used to download to your computer, for example, any incoming voice over the phone and IPTV (internet television). The spectrum used for television channels is 1550. All of these are industry standard and all providers use the exact same.
