That's exactly what I needed to know Thanks!

Sorry let me rephrase my question in a better manner if the electrons are accelerated (maybe in a vacuum?) to a KE are between the first and second "threshold" (KE required for the electrons to lose energy in the collision with the mercury atoms) prior to allowing them to enter the mercury...

Thanks I like your first point. I will keep that in mind Your second point is exactly what I am thinking. I had trouble understanding how the pair creation is evidence for the quantum nature. Thanks

There is a basic quantum mechanic class on udemy.com by a physicist called Marco Masi

Hello, Thanks for the reply If the energy is lost in a non elastic collision when the voltage is 4.9voltage, then i see how the energy at 6v would be reduced once the voltage is increases. But how will the energy be lost if we never pass through the 4.9v? is it cause the KE will have to...

I have a question that might be very basic. The Franck-Hertz experiment shows that as the voltage (KE of the electrons) increase, the current/energy of the electron increases up to 4.9v at which point it drops due to the non elastic collision. this happens at intervals of 4.9v. assume that the...

Thanks! I am excited

Hi I have started studying Quantum Mechanics on my own and I had a question that I am stuck on. I apologize if it's too basic or if someone else asked it I understand what Pair Production is, but the source I am learning it from is saying that Pair production, is another way to prove the Quantum...

I am Ghaleb I am an engineer, and there is a lot i don't know that I am learning on my own!
