Modern Physics Laboratory establishment help

Click For Summary

Discussion Overview

The discussion revolves around establishing a modern physics laboratory for sophomore university students. Participants suggest various experiments and considerations for the lab's setup, focusing on both theoretical and practical aspects of modern physics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant suggests including experiments such as measuring Blank's Constant and the e/m ratio for electrons.
  • Another participant proposes additional experiments, including the photoelectric effect, the Millikan oil drop experiment, electron diffraction, and the hydrogen spectrum using a spectrometer.
  • A suggestion is made to include simple experiments with a Michelson interferometer, although its use for the Michelson-Morley experiment may not be feasible in a student lab setting.
  • One participant raises questions about the necessary information for providing advice, such as projected student enrollment, existing lab equipment, budget constraints, and the balance between computational and experimental work.
  • A participant shares their experience with x-ray diffraction experiments and measuring crystal lattice constants, as well as measuring decay rates of radiation sources.
  • Several links to resources for ideas and equipment help are provided by participants.

Areas of Agreement / Disagreement

There is no clear consensus on the specific experiments to include, as participants offer a variety of suggestions and considerations, indicating multiple competing views on the best approach to establishing the lab.

Contextual Notes

Participants express uncertainty regarding the necessary infrastructure, budget, and student enrollment, which may affect the feasibility of suggested experiments.

Hi all
First of all, I don't know whether this is the right sub-forum to post at, so forgive me if it is not.

I have recently been asked to establish a modern physics lab for university students at sophomore level, so what experiments do you suggest to found the lab.

I've included the following experiments:
-measuring the Blank's Constant
-measuring e/m ratio for electron

so what else do you suggest to include

thanks
 
Science news on Phys.org
Photoelectric effect.
Millikan oil drop experiment.
Electron diffraction.
Hydrogen spectrum and Rydberg's constant, using a good-quality prism or grating spectrometer.

Perhaps a few simple experiments with a Michelson interferometer, although you won't be able to do the Michelson-Morley experiment with one that can fit on a student lab table; this is probably better as part of an optics course if you have one.
 
It's hard to offer advice without any information- for example, how many students are projected to be enrolled? What sort of infrastructure/lab equipment do you already have, and what is your budget for new equipment and supplies? What is the balance between computational and experimental lab work?

etc. etc.

Millikan oil drop experiment.

I'm curious whether undergraduate labs are able to routinely get the right value from their Millikan experiments?
 
When I was in modern lab, I also did an experiment on x-ray diffraction, and measuring crystal lattice constants along with an experiment on measuring the decay rate of some radiation sources.
