Animation, reflection, reflection law, optics

In the intercative animation on the reflection law, the geometric relationships between the angle of incidence and the angle of reflection are illustrated.

Tip: You can move the spotlight interactively with the mouse. All gray points are also movable.

You can zoom in and zoom out the rectangle in the animation by clicking on it.

The animation was developed as a offline application for Windows and Macintosh systems and for integration into Microsoft PowerPoint slides. The online version presented here serves as a preview. The exe or app file can be downloaded free of charge in the member area.

The animation shows a spotlight that illuminates a surface. The shape of the surface, the position of the radiator and the orientation of the radiator can be changed. Depending on the angle of incidence, the light beam (in accordance with the rule "angle of incidence = angle of reflection") is reflected differently.

For the clarification of the reflexion law, the angular labels can be blend. The angle of incidence, the angle of reflection and the solder are depicted. In addition, a refracted light beam is also drawn, for example, in the case of a partially transparent medium.

The shape of the surface can be changed with the mouse interactively. As a result, in addition to a straight surface, different curved and wavy surfaces can also be represented. The light source is represented by a radiator. Both the position of the light source and the target point of the light beam can be moved interactively with the mouse. Just click on the corresponding points.

Note: The orientation of the radiator is changed by moving the gray point around the lower edge of the rectangle. The radiator is directed to this point.

In all interactions, the complete display adapts seamlessly and in real time. This also applies to all markers and labels. In addition to the angle of reflection, a refraction angle is also shown.

Electromagnetic induction by rotating magnets (simplified)

Die Animation zeigt ein Objekt, dessen reflektiertes Licht durch eine Linse fokussiert wird. Je nach Brennweite und Gegenstandsweite liegt der Fokuspunkt an unterschiedlichen Positionen
Visualization of the lens equation

Die Animation zeigt eine Linse, die einen Lichtstrahl fokussiert. Jeder Farbanteil des Lichts bildet einen anderen Fokuspunkt.
Principle of chromatic aberration

Die Animation zeigt eine Linse, das einen Lichtstrahl fokussiert. Aufgrund der sphärischen Aberration entstehen unterschiedliche Fokuspunkte.
Principle of spherical aberration

Die Animation zeigt eine Linse, dessen numerische Apertur interaktiv verändert werden kann. In Abhängigkeit von der numerischen Apertur verschiebt sich der Brennpunkt der Linse.
