Fireworks lighting

With all of their noise, different colors, and different patterns, fireworks light up the summer sky and put on a fascinating and exciting display. But how do fireworks work ... [Pg.3]

Whether chemical reactions are used to make plastics, diagnose disease, catch criminals, or for entertainment purposes, life would be very different without them. Indeed, without certain chemical reactions, life would not exist at all. When we eat, light a candle, watch a firefly or fireworks light up the summer sky, or engage in any number of other activities, chemical reactions occur. In fact, they are happening all around us—all the time. [Pg.84]

Classification of firework light sources 2 Standard diameters of round flowers 3. Experimental values of critical wind velocity Detonation velocities of report compositions 5. Observed flame temperature for representative fuels... [Pg.345]

Chemicals are also involved in entertaining us. Our lives would be desolate without their efforts to entertain us. A few areas where we are entertained by chemicals are talked about in this part, including fireworks, light show by firefly and others, ceramic artworks, diamonds, and perfumes. One of the emphases here is the basis of the visual arts, i.e., the phenomenon of color. ... [Pg.109]

Fireworks displays are fascinating to watch. Neon lights and sodium vapor lamps can transform the skyline of a city with their brilliant colors. The eerie phenomenon of the aurora borealis is an unforgettable experience when you see it for the first time. All of these events relate to the generation of light and its transmission through space. [Pg.133]

Light fireworks at arm s length, using a taper or a fireworks lighter. [Pg.91]

C07-0111. Barium salts in fireworks generate a yellow-green color. Ba ions emit light with A = 487, 514, 543, 553, and 578 nm. Convert these wavelengths into frequencies and into energies in kJ/mol. [Pg.497]

Eor example, street lamps use the emissions from excited sodium atoms, the dazzling colors of a fireworks display come from photons emitted by metal ions in excited states, and the red light in highway flares often comes from excited Sr ions. [Pg.533]

Pyrotechnics are often used in the production of fireworks and primers. A pyrotechnic contains both a fuel and an oxidizer formulated to produce a lot of energy. The energy is then used to produce a flame or glow (matchstick) or combined with other volatile substances to produce smoke and light (fireworks) or large quantities of gas (firework rockets). [Pg.56]

But who wants to see a supersonic rocket full of smokeless propellant disappear into the heavens like a flash of light when one can witness the leisurely ascent of a firework rocket as it climbs leaving a graceful trail of sparks ... [Pg.60]

Potassium chlorate is an oxidizing agent in matches, fireworks and explosives. The head of safety matches is coated with potassium chlorate which is struck on a surface consisting of red phosphorus, antimony(lII) sulfide and an adhesive to light the fire. It also is used in laboratory preparation of oxygen. Its dilute aqueous solution is an antiseptic. [Pg.745]

Magnesium metal is the fuel found in most military illuminating compositions, as well as in many fireworks devices. Aluminum and titanium metals, the magnesium /aluminum alloy "magnasium," and antimony sulfide (Sb2S3) are used for white light effects in many... [Pg.84]

Sometimes, the celebration of a major event is accompanied by a spectacular firework display. In particular, firework displays are a traditional way of commemorating great victories in war the loud explosions and brilliant flashes that light up the sky recapturing the thrill and excitement of battle while allowing the whole experience to be enjoyed in safety. But how are these gloriously noisy and colorful displays produced ... [Pg.10]

Fireworks are displays of colored lights, noise and smoke used on occasions of public celebration also the devices used tor such displays... [Pg.416]

Fireworks are a part of die field of civilian pyrotechnics (Greek pyr, fire techne, art) the rest of the field is railway fusees and torpedoes. Military pyrotechnics includes lights for signals and illumination, noise makers for training, heat sources, smokes, and some minor rocket effects. Many of the same formulas and devices are used in both fields with the military devices more sturdily built... [Pg.416]

Other light sources, however, emit a distinct number of discontinuous colors. Examples include streetlights, neon signs, sparklers, and fireworks. The spectral patterns... [Pg.151]
