Quantum physics experiments for EEI

Click For Summary
The discussion revolves around finding a suitable quantum mechanics experiment for a Year 12 physics Extended Experimental Investigation (EEI). Participants emphasize the complexity of quantum physics and the challenges of conducting experiments due to the need for specialized equipment. A suggested experiment is a variation of Young's Slits, which is more accessible and involves wave interference theory. It is advised to clearly define the experiment's focus and ensure that data is collected from the experiment itself rather than relying on theoretical calculations. Clarity and adherence to the experiment's objectives are crucial for success in the EEI.

(Hope this is the right forum)

For my year 12 physics EEI (extended experimental investigation) basically a report. I was hoping to find a suitable quantum mechanics experiment that i could conduct. Does anyone know of an experiment like this?

Thanks in advance

Welcome to the PF. :smile:

What are your ideas so far? What research have you done so far on this?

Hey, are you from Australia? I remember doing E.E.I.s... God I hated them. Well done doing quantum physics as a topic for your E.E.I. though. Complex and challenging, right? That sounds like a hard topic to do not only because the theory is difficult but it is difficult to do an experiment on (I think you would need very special equipment). The simplest thing I can think of is to do something similar to Young's Slits, which doesn't require a lot of equipment and the theory (wave interferences) is not too complicated.

My best advice for doing an E.E.I., however, is to make it as clear as possible what you are testing. You are doing an experiment to see what the natural phenomena you observe is, what the theory behind it is, and if it is consistent with that theory. Do not use theory to produce the data for you! For example, do not do mathematical calculations (a priori) to produce your data. The data must come from your experiment (a posteriori) and then you see if the data is consistent with the mathematical theory.

Good luck!

EDIT: Just another point to add: I am also saying don't go too far off on tangents. Be clear about what you are testing and stick to it.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
