Help with my lab? (Atomic Spectra)?
One of my problems says:
A particular transition of the rubidium atom emits light whose frequency is 3.84 x 10^14 Hz. Is this light in the visible portion of the spectrum? If so, what colors is it?
I solved it using the λ ( f ) = C and got λ = 781 nm. However, the wavelength of visible light is 400 to 750 nanometers. I am not sure what to do, can anyone help me out?
Will chose a best answer. Thanks =]
Your calculation is correct. The wavelength is 780.71 nm.
It is a somewhat unfair question, since the upper limit of the visible spectrum is different depending on the source. Some sources cite values as low as 700 nm, while others cite 780 nm (ICNIRP).
Being over 780 nm, I would certainly say it's invisible, it is the beginning of the NIR (Near InfraRed) part of the spectrum. Besides, for any practical needs and purposes, this is invisible.
