Question

What is the wavelength in nanometers of a photon of light that has a frequency on 1.5 x 10^15 hz

Answer 1

Equation:  

Ф = v / f where Ф is wavelength, v is velocity of wave (which is usually the speed of light 300,000 km per second, and f is frequency.

Ф = (300,000) / 1.5x10^15

Answer 2

We have been looking at the wave properties of electromagnetic radiation. ...  thewavelength and frequency of photons with the following energies: Ephoton=1200 eV (x-ray) 1.0 nm3.0x10-17 Hz; Ephoton=4.2x10-19 J (blue ... MeV/c2 ) 8.2x10-14 J 0.51 MeV; Proton (1.67x10-27 kg)1.5x10-10 J 0.94
