WebApr 1, 2000 · As light travels very fast – around 186,282 miles per second – the heated air inside the clouds doesn’t get time to expand; thus, it gets compressed and raises the pressure and temperature. This creates rapid expansion, which produces sonic shock waves that result in thunder. Can you calculate how far away lightning struck by thunder? WebSep 26, 2016 · The experimental speed of light in air is: 3 * 10^8 m/s Therefore, the frequency of this beam of light is: v = fλ; where v is speed, f is frequency, and λ is the wavelength. The frequency thus is: 3×10⁸ / (670 × 10⁻⁹) = 4.48 × 10¹⁴ Hz The frequency will remain the same in the solid medium The speed will then become:
