What is the wavelength of radiation that has a frequency of 5.80×1014 s−1 ?

Speed of radiation, c = 3.00 × 10⁸ m s⁻¹
Frequency, f = 5.80 × 10¹⁴ s⁻¹

c = f λ
Wavelength, λ = c / f = (3.00 × 10⁸ m s⁻¹) / (5.80 × 10¹⁴ s⁻¹) = 5.17 × 10⁻⁷ m
OR: 517 nm

For any wave v = f * lambda where v = speed, f = frequency and lambda = wavelength. Plug in the numbers.

Electromagnetic radiation moves at the speed of light.
