How can I find the wavelength of blue light if it has a frequency of 6.67 x 1014 sec (Hz)?

Question

Thanks ahead!

Answer 1

wavelength=v/f

since we're talking about light, v=c (the speed of light, 3 x 10^8 m/s).

Thus, the wavelength is
(3 x 10^8 m/s)/(6.67 x 10^14 Hz)

Answer 2

Lancenigo di Villorba (TV), Italy

In the XVII century, G. Galilei tried a trivial experiment to determine the "light's speed".
Some centuries later, J. C. Maxwell stated the differential equation related to "Electro-Magnetic Wave" 's in the surrounding space. These equations lead to calculation of the "E.M. wave's speed" like 3.0E+8 m/s.
Light and the other E.M. waves run at the overwritten speed.
Starting from the following relation

(E.M. wave's speed) = (frequency) * (wavelenght)

Wavelenght = E.M.W.'s speed / frequency =
= 3.0E+8 / 6.7E+14 = 4.5E-7 m = 450 nm

I hope this helps you.

Answer 3

lambda = c / frequency

lambda = 3 *10^8 / 6.67 *10^14

lambda = 450 nm
