experiment 1: what is the mass/length ratio of the initial marked bluegill population? the mass/length ratio is determined by dividing the average length of the population by the average mass.

Hydrogen atoms are excited by a laser to the =4n=4 state and then allowed to emit. what is the maximum number of distinct emission spectral lines (lines of different wavelengths) that can be observed from this system? 8 6 2 7 4 5 1 3 calculate the wavelength of the 4⟶14⟶1 transition. =λ=
