Practice Problem: The Bohr Model and Photon Wavelength

With the Bohr model we start to get a better sense of the nature of matter, particularly the way light interacts with atomic matter such that we can see it. But how do we do calculations regarding these interactions? Let's practice now!

Thanks a million, you're one of the best professors I've ever seen. Great explanation for each topic!

[@georgemakarri7004]

This takes practice but the equation manipulations help a ton, was clueless before trying to plug in each value into the equation. Still need some work but thank you very much for making it easily understandable!!

[@DapaChrons]

thanks for the extra practice!

[@chemstudyworld]

Thank you so much sir. Great help..

Where did you get the 2.178x10-18? Shouldn't it be the -13.6 eV value converted in Joules?

Can you please explain why the energy associated with each orbit is the same, but different elements emit different wavelengths when excited? Quantum mechanics stuff? Maybe you did in your video, fixing to watch, ty

Professor, you know anything about LENR (low energy nuclear reactions )??

Sir, Please tell. Can electrons exist independently??
Please tell Sir.

independently of atoms? of course.
