Principle Care is to be taken in particular that the experimental setup is not shifted during the experiment, in particular the ruler because otherwise no reference point for the comparison of the measuring curves is available. Furthermore, this experiment has to be carried out in a completely dark room. Benefits
Tasks What does the spectrum of a light emitting diode look like? When we observe the white LED through a grating we can see
colour components across nearly the entire spectrum. Because our
eye cannot see the individual frequencies objectively but
overemphasises the green range it is difficult to say which
intensities the individual colour ranges have. An absolute
comparative determination of intensity is hardly possible.
