Mirror
A flat mirror: reflects a ray by the law "angle of incidence equals angle of reflection".
How to add
In the left Instruments and experiments panel, Light and lenses section: click the element and it appears in the centre of the frame. Rays are traced instantly, no need to run the simulation. Rotate the mirror and change its length.
Properties
- Angle
- Mirror rotation.
- W and H
- Length and thickness of the mirror.
Tips
- Two mirrors at an angle make a periscope; several mirrors send the ray along a long path.
- To check the law of reflection, add captions with the angles.
