A sample of Ca is excited electrically, resulting in the emission of light with energy 3.09x10-19 j per atom.
Frequency? wavelength? color? Bernouli's equation dN/dt = 0.095 N - 0.01N^2 N(0)=100? Taking calc 1 im not sure what i did wrong with this problem..? The only line emissions detectable by the eye for hydrogen correspond to transitions for e- dropping from higher energy level to n=2. Why? Define gravity to me?
