Lasers and mirrors

HOW

Left side

Use the manipulators to explorehow laser beams behave when reflected from a mirror of a chosen curvature:

1. flat,
2.convex,
3.concave.

Right side

Position the optical elements so that the laser beam is directed towards the bottom of the black rectangle.

WHY

On the left-hand side you can see that the reflection angle of a beam of light from a mirror is equal to its angle of incidence.

It can be concluded that the reflected beams:

1. are parallel for a plane mirror,
2. move away from each other for a convex mirror and their extension on the concave side is focused on one spot,
3. are convergent to the point for a concave mirror.

The points of intersection of the beams or their extensions are the focus of the mirror.

You can use your knowledge of the law of optics to properly direct the laser beam on the right-hand side.
