Please see various quantum questions on wavelengths and laser behavior attached.
Showing work or giving explanations would be much appreciated.
Please see attached Word document. Everything you need is in there.
If you need more help, just ask. Thanks for the work!
P.S. I've pasted in the document here below, but don't worry about that. It looks way better and is much easier to follow in the Word document.
1. a. What is the wavelength (in meters) of electromagnetic radiation broadcast by an FM radio station with a frequency of 106.1 MHz?
That means that the wavelength () times the frequency () = the speed of light (c).
106.1 MHz is frequency (s-1)
M = Mega = 1x106
Therefore, 106.1 MHz = 106.1x106 Hz = 1.061x108 Hz = 1.061x108 s-1
To find wavelength, we rearrange the equation like this:
Now, we just solve for wavelength ().
 = (3.00x108 m/s)/( 1.061x108 s-1) = 2.83 m
b. What is the frequency (in Hertz) of electromagnetic radiation with a wavelength of 532.6 nm?
You do this one the same as the first question, except here you're starting with wavelength and have to calculate the frequency.
nm = nanometer = 1x10-9 m
Therefore, 532.6 nm = 532.6x10-9 m = 5.326x10-7 m
Rearrange the equation to look like this: ...

Rate Limiting Steps in Metal Oxide Epitaxy
On the bottom right-hand side of the third page of the pdf attached (page 2 of the article), the author states:
"Metal deposition rates are easily converted into the oxide growth rate under the assumption that the metal arrival rates are the rate limiting steps, which is true for growth under oxygen- rich conditions."
I am having trouble understanding this, so please answer the following questions to clarify it for me.
(a) What is meant by metal arrival rates being "rate limiting steps?" (Does this refer to oxidation?)
(b) Why is this true? (Why are metal arrival rates rate limiting steps?)
(c) What exactly is meant by an "oxygen-rich environment?" I haven't seen a technical definition of an "oxygen-rich environment" anywhere in the literature.View Full Posting Details
