Principle

Because stray light cannot enter the LED on account of the tube, this experiment can also be carried out in daylight. In this experiment you will learn to record a characteristic and to interpret it.

Benefits

Specified for the requirements of the german final secondary-school examinations
Especially for secondary schools
Quantum and wave optics in a student experiment

Tasks

What does the UI characteristic of an LED look like? A light emitting diode (LED) is a semiconductor component which has a characteristic curve. A component can be caharacterised by the relationship between the applied voltage and the measured current.
