ν = c / λ = 3.00E8m/s / (436E-9)m =
λ = c / ν = 3.00E8m/s / (5.2E14)/s =
The only difficulty here is making sure you use proper scientific notation in your calculator entries.
If you enter it as 3x10^8 / 436x10^-9 you'll get the wrong answer because order of operations results in this slightly different calculation (3x10^8 / 436)x10^-9; you're multiplying by 10^-9 instead of dividing by 10^-9.
