#28 Atomic Spectroscopy Post-Assessment for module

Postby Ramsha Dis1B » Wed Oct 24, 2018 10:06 pm

The problem is:

The meter was defined in 1963 as 1650763.73 wavelengths of radiation emitted by krypton-86. What is the wavelength of this krypton-86 radiation?To what region of the electromagnetic spectrum does this wavelength correspond? what energy does one photon of this radiation have?

I did not know how to determine the wavelength because I feel like I don't have the information that I can use to find the wavelength? Can someone please tell me how to find the wavelength?

What I did was that since it says "the meter" was defined as 1650763.73 wavelengths, I divided 1 meter / 1650763.73 wavelengths. I think this should get you one wavelength.
