"Any light beam moving vertically downwards in the concavity of the parabola (parallel to the axis of symmetry) will bounce off the parabola moving directly towards the focus." http://en.wikipedia.org/wiki/Parabola
No, it is not an optical illusion.

No. If you tilt a parabola, you will still have a parabolic curve but it will no longer be a parabola.
what are the effects of the sign a and n to the parabola
A parabola is a curved shape that is plotted on the Cartesian plane.
No, it is not an optical illusion.
none as you have given no options
This category covers establishments primarily engaged in manufacturing instruments and apparatus that measure an optical property
it is an chemical property by giving off the glow. Triboluminescence is an optical phenomenon, consequently is a physical property.
It should be opaque

A parabola is NOT a point, it is the whole curve.
projectile motion
A parabola opening up has a minimum, while a parabola opening down has a maximum.
Luster is an optical phenomenon, the effect of interaction between light and a crystal.
