What is the frequency of light having a wavelength of 447 nm?
Wavelength = Velocity / FrequencyTherefore:Frequency = Velocity / WavelengthVelocity = c, the speed of light, which is 299,792,458m/s.We know the wavelength is 413nm, which is 4.13*10-7m, so our equation is:f = (3.00 * 108) / (4.13 * 10-7) = 7.259 * 1014Hz
What is the name of Nikola Tesla invention?
