Laser Beam Geometry Prediction

A laser light demonstration takes place in the creator's son's room, projecting a laser beam onto the wall.

• For cyclic inputs, the laser creates a line pattern • For collective inputs, the laser creates an arc pattern • The challenge is to explain why these different geometries occur

Determine whether the arc shape is a parabola or a hyperbola and defend your answer with mathematical reasoning.
