Homework Statement
The hydrogen spectrum contains a blue line with a wavelength of 434nm. Photons of blue light are emitted when hydrogen's electron drops from the fifth energy level to a lower energy level. What is the lower energy level?
Homework Equations
1/wavelength = R [ 1/n2^2 - 1/n1^2]
The Attempt at a Solution
1/(4.34*10-7m)= (1.097 x 10^7 m^-1) [1/n2^2 - 1/5^2]
2,304,147/(1.097*10^7) = 1/n2^2-0.04
0.21n2^2=1
n2=2.182
thus i found that the lower energy level is 2 , is this correct ?
