Light
Properties and Experiments
"At night all cats are black." – all of you will probably know this figure of speech. Light is involved or rather a situation where little light is available. In order to be able to see well we need not only keen eyes but above all light. Although our eyes adapt to dark surroundings, we hardly see any colours anymore and perceive only the silhouette of the cat or any other object. Light is the visible part of electromagnetic radiation and consists of tiny mass particles. The so-called photons move at extremely high speed and carry an immense amount of energy. We cannot touch it but feel and observe its effects. Light is a precondition for us to be able to take photos, watch a film or view something under a microscope. A lot of fascinating natural phenomena – for instance a bright blue summer sky or a rainbow – are based on light. Without light, life could not have evolved on earth. Light is energy – the chlorophyll of plant cells or solar panels can convert it into other forms of energy. Today we know what light energy is, what effects it produces and how it can be used.

Copyright
Copyright is subject to constant change to keep up with technological advances. This film enables the viewer to grasp the basic principles of this extremely intricate matter. By way of introduction, the film defines what an author is, what kinds of works there are and how long a work is protected on principle. Then the fundamental rights of an author are cited and it is shown how these are exploited in our times. In the third chapter, the respective rights are illustrated by way of practice-oriented examples of books, photos, music and films. Here, of course, an emphasis is laid on the field of education, taking into account the latest case law within the EU and Austria in particular. A further chapter highlights the problems arising with the Internet and goes into the citation law and pirate copies. All in all, in this way the viewer is made familiar with the most important basic terms and their meanings. Comprehensive worksheets and additional accompanying material invite us to deepen our knowledge of the subject.
