created by vaporization of liquid which causes expansion of the liquid and therefore making a shock wave. Fireworks are also used in television quite frequently and have a lot of chemistry behind the scenes. This includes the different metals changing the color‚ the gunpowder to fuel the explosion‚ and finally the ingredients such as charcoal and potassium nitrate that are what make the reaction. Another common television art and magic illusion is invisible ink. Invisible ink was first used over

disease. You will use a procedure to transform bacteria with a gene that codes for Green Fluorescent Protein (GFP). The real-life source of this gene is the bioluminescent jellyfish Aequorea victoria. Green Fluorescent Protein causes the jellyfish to fluoresce and glow in the dark. Following the transformation procedure‚ the bacteria express their newly acquired jellyfish gene and produce the fluorescent protein‚ which causes them to glow a brilliant green color under ultraviolet light. In this

Waves effect our everyday life in many ways. Waves are very interesting ways to travel‚ and we don’t mean surfing! Many things we use every day involve waves. Lights and sounds are examples of everyday uses that travel by wave. On the spectrum of light there are waves listed which are X-Rays‚ UV-Rays‚ and Infrared. Some of these are harmful to life‚ and some of these are helpful to life‚ where mostly they all serve both of these purposes. Another type of wave‚ though not on the spectrum because it

Germanium- Germanium is a very important semiconductor. The pure element is doped with arsenic‚ gallium or other elements and used as a transistor in thousands of electronic applications. Germanium is also finding use as an alloying agent‚ in fluorescent lamps and as a catalyst. Both germanium and germanium oxide are transparent to infrared radiation and so are used in infrared spectroscopes. Germanium oxide has a high index of refraction and dispersion and is used
