I am in a General Chemistry class but we are on the chapter: Quantum Theory and Electronic Structure of Atoms. I do not understand my teacher and want some kind of real human being to explain to me how to find an answer to the question I'm going to give. Please do not think that I'm cheating on homework or anything, I want to know how and why the answer is what it is not just a quick answer.

Here is the question: What is the wavelength (in nanometers) of light having a frequency of 8.6 x 10^13 Hz? What is the frequency (in Hz) of light having a wavelength of 566nm?

Thanks to anyone who can help (or give me a joke to laugh at) :smile:
 
Physics news on Phys.org
How do speed, wavelength, and frequency relate for any wave? (Hint: Consider the units of each.) What's the speed of light?
 
Do you know the equation which relates the frequency and wavelength of a wave through its velocity of propagation?

[itex]\nu \lambda = c[/itex]

- Warren
 
the answer above is right
 
maybe the threadstarter want to know why is the equation [itex]\nu \lambda = c[/itex] ?

I believe that was Doc Al's point.
 
So, a priest, mininster, and a rabbi may have walked into a bar...
 


I understand what Doc Al and Chroot are both getting at. So after using the equation that was given by Chroot I should convert the answer into nanometers?
 
If they want the wavelength in nanometers, give them nanometers!

1 nm = [tex]10^{-9}[/tex] m

Ha! They MAY have walked into a bar? Did they or didn't they?

Thank you! I shall give them nanometers!

...nanometers that destroy:devil:

No but seriously thank you o:)
