Post Assessment #25

Postby Jacinda Wollenweber 1D » Tue Jul 11, 2017 9:35 pm

The meter was defined in 1963 as 1,650,763.73 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?

Can I get some help solving this problem please?!

1,650,763.73 wavelengths = 1 m

Therefore 1 wavelength = 1 m/1,650,763.73

With the wavelength calculate frequency.
With the frequency calculate E.

I need to sleep otherwise I'll arrive late to hand out exam 1.
