General Chemistry 1: Quantum Theory

An infectious organism can be completely destroyed by irradiation of UV light with a wavelength of 254 nm. What is the frequency of this radiation?

Calculate the energy of a mole of photons of blue light ( 4.00 x 10##^2## nm )

Rank the following wavelenths in order from lowest energy to highest energy: (Hint: for comparison, units should be the same)
500 nm
190 nm
250 mm
320 ##\mu##m

When n = 7, list all valid sets of quantum numbers.
