Answer 2

I dont know how to speak it mathematically but I know if you move the lamp closer to the wall the angle that the light reflects will make a circle on the wall but idk what a paraboila is or a hyper bolia is, i assume its the half circle under it. I know i didnt help much but i hope i did.

Answer 3

As the plane moves faster than the speed of sound, you get a cone-like wave.
Where the cone intersects the ground, it is an hyperbola.

The sonic boom hits every point on that curve at the same time. No sound is
heard outside the curve.
