what is the wavelength of blue light if it has a frequency of 6.67 x 10^14 sec (Hz)?

4 answers

c = f*l

c = speed of light
f = frequency
l = wavelength

c = 3x10^8 m/s [a constant]

l = c/f

l = 3x10^8/6.67x10^14
l = 4.49775x10^-7
l = 449.8 nm

Hope that helps
Watch the s.f.
Ah, I should have the same as the original figure - 2 decimal places. Thanks!
