Exp 1: Photoelectric Effect

This device can be used to show that the energy of light is proportional to the frequency of the radiation and independent of the intensity of the radiation

Exp 1: Photoelectric Effect

Planck's constant with data from the documentation

This experiment didn´t work The beam was not aligned The operational amplifier didn´t work correctly It seems nobody has done measurements since

last yearWhen touching wires the measurements change Not appropriate for our students

Proposals for gifted students

An international experience for high school students (16-17 yrs)

Teachers´ Lab a friendly place

Teachers´ Lab a place to invent new experiments in

Modern Physics

Conclusions

The proposed experiments require continuous maintenance

It is necessary to re-think and re-write the documentation of all the experiments

It would be great to find new experiments less expensive

A Teachers´ Lab in the Microcosmos Exhibition requires someone to supervise, maintain and explain the experiments
