c = f λ
where c is the speed of light in a vacuum (m/s^2), f is frequencey (cycles per second or Hz), and λ is wavelength (m).
Solving for lambda gives λ = c / f
c = 3 x 10^8 m/s
f = 3.5 x 10^14?
λ = c / f = 0.857 x 10^-6 = 857 nm

wavelength = speed/frequency
=(3 x 10^8m/s)/ (3.50 x 10^14 Hz)
= 857 nanometers

wavelength = speed-of-light / frequency
wavelength = 3.0*10^8 / 3.50*10^14
(wavelenth will be in units of: meters)
You can do the rest on your calculator.

the formula is : wavelength = frequency * velocity
