Using the conversion factor from ev (electron volts) to joules, determine which energy line for an electron dropping from one energy level to another would show a line at 435 nm in an emission spectrum. use the formulas and the energy level information below to answer the question.
needed constants:

1.00ev = 1.6 * 10^-19 j
c = 3.00 * 10^8 m/s
h = 6.63 * 10^-34 j*s

energy level values:
e6: e= -0.378 ev
e5: e= -0.544 ev
e4: e= -0.850 ev
e3: e= -1.51 ev
e2: e= -3.403v
