How do Fireworks get their colours?
Fireworks have an outside shell that’s called a mortar. It can be made of many things including cardboard, papier-mache or plastic.
Inside the mortar are compartments. The bottom compartment is filled with black powder (potassium nitrate, charcoal and sulfur) that will be the fuel for the firework.
The top compartment contains the pyrotechnic stars that make the colors and shapes we love to see. The stars are made of a fuel that burns and minerals and metals pressed together provide the color. The way the stars are arranged in the mortar provides the shape of the firework, like ovals, stars or rectangles.
Stars contain five basic types of ingredients.
• A fuel which allows the star to burn
• An oxidizer—a compound which produces (usually) oxygen to support the combustion of the fuel
• Color-producing chemicals
• A binder which holds the pellet together.
• A chlorine donor which provides chlorine to strengthen the color of the flame. Sometimes the oxidizer can serve this purpose.
Some of the more common color-producing compounds are Barium which produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. Other colors can be made by mixing elements: strontium and sodium produce brilliant orange; titanium, zirconium, and magnesium alloys make silvery white; copper and strontium make lavender. Gold sparks are produced by iron filings and small pieces of charcoal. Bright flashes and loud bangs come from aluminum powder.

How does a Parabolic Antenna work?
An antenna has an active element that picks up or sends out radio waves. This active element is the one connected to the electronic circuitry. An antenna is essentially a transducer. It converts electrical energy into electromagnetic energy as as way of coupling the electronic circuit to the medium of communication called free space.
Dish antenna is curved so that all the radiation that strikes it is reflected to converge at one single point - its focus - where the amplifier or the receiver is placed. It is a parabolic reflector - a curved surface with the cross-sectional shape of a pararabola that directs the incoming waves to the focal point. This enables the maximum signal strength.
The same reason why a concave mirror is used in a reflecting telescope; it gathers all the photons and focusses it to one single point.
The satellite is situated in an orbit about 22,000 miles, or 36,000 km for those who like to count in tens, up. At this point the orbit of the satellite matches that of the Earth, and so for all practical intents and purposes it occupies the same place in the sky constantly when viewed from the ground.
It sends out radio waves. Typically satellites will operate either in the C band (3.7 to 4.2 GHz) or the Ku band (12 to 18 GHz).
The reason we have two is because of the characteristics of each. The C band is highly susceptible to ground fade but not rain. The Ku band is highly susceptible to rain fade but not ground. Consequently where there are densely populated areas where it doesn’t rain much, Ku is better. In remoter areas where you may get a monsoon, C band is a better choice.
