The wavelength of green light from a traffic signal is centered at 5.20 x 10-7 m.
Calculate the frequency.


Answer :

Answer: 5.77 * 10¹⁴s⁻¹

Explanation:

Speed = Frequency * Wavelength

Frequency = Speed/ Wavelength

Speed of light = 3 * 10⁸ m/s

Frequency =  (3 * 10⁸ m/s) / (5.20 x 10⁻⁷m)

= 5.77 * 10¹⁴hz

= 5.77 * 10¹⁴s⁻¹
