Atomic Spectra Post Mod Q

Postby Rose_Malki_3G » Tue Oct 06, 2020 1:39 pm

The meter was defined in 1963 as 1,650,763.73 wavelengths of radiation emitted by krypton-86 (it has since been redefined). What is the wavelength of this krypton-86 radiation?

How would you solve this problem?

Since you are told that 1 meter is 1,650,763.73 wavelengths of radiation emitted by krypton-86, it is basically a 1 meter to 1,650,763.73 wavelengths ratio. To find 1 wavelength, just divide 1 meter by 1,650,763.73.

If you set it up as 1m=1,650,763.73 wavelengths, then your goal is to find 1 wavelength, so divide both sides by 1,650,763.73 to get your answer.
