How does light enter the world?
How does light enter the world?
Prof. Dr Mathias Wickleder
Institute of Pure and Applied Chemistry
It is impossible to imagine our world without light! Whilst our ancestors still had to live by the natural rhythm of night and day, we simply switch on the light! And nowadays, this light no longer comes mainly from a simple light bulb, as invented 110 years ago, but from sophisticated and highly advanced light sources such as ‘halogen lamps’, ‘xenon lamps’ or ‘LEDs’. There’s a whole lot of chemistry going on inside these modern lamps! This lecture uses a range of experiments to show which chemical reactions play a key role. But you’ll also see that even some animals – such as fireflies and bioluminescent fish – manage to bring light into their world!
