Sapling #24

Postby Katie Phan 1K » Sun Nov 01, 2020 10:52 pm

Hi. I'm having some trouble with the homework question pertaining to the wave patterns associated with the Bohr orbits of the hydrogen atom. Could someone explain to me what a sinusoidal and constant wavelength around the orbit looks like?

Sinusoidal means that a FULL "sin" wavelength has been completed, so the examples that have half a cycle on the end are not compatible (even though they look uniform).

A sinusoidal wave is symmetrical, and "normal" looking for a wave (aka like a sin-wave).

A constant wavelength means that the wave does not have two wavelengths. The entirety of the wave is symmetrical (like a mirror image) around the orbit (the line going through the center of the wave).

Finally, the wave that fulfills the Bohr and Broglie models must be continuous when it is circled around the nucleus (aka the beginning of the wave must be the opposite of the end of the wave).

Hope this helps!

I second Claire, make sure that they start and end at the same point, like you could connect the beginning of the wave to the end and it would still flow evenly.

So basically what you have to keep in mind is that in order to move to a larger orbital, you have to expand the orbital exactly so that the wave connects exactly with itself (because e, which follow orbital paths, have wave-like tendencies).

If you add the picture of the line side by side they should be continuous. That’s how you will know

I agree ^ If they start the same it should end the same. Make sure the wave has a pattern. :)

I was confused on this one as well, but I realized that the waves must be continuous. So as Juliana mentioned above, picture the image of the wave side by side, and if its continuous, then you know that the wave is compatible.
