What is the frequency of green light with a wavelength of 532nm?

Answer 1

Preliminary note: People (including physicists) often describe light and other EM radiation by its wavelength. It's important to note that this is meant to refer to its wavelength in a vacuum. Because the speed of light is lower in any other medium (i.e., in any kind of "stuff") the wavelength is reduced. This effect in miniscule in air, but quite substantial in other things like glass or water. It is frequency that remains fixed as light goes from one medium to another, not wavelength. So, the answer below is to the question "What is the frequency of green light with a vacuum wavelength of 532nm?"

Electromagnetic frequency, f, is equal to the speed of light, c, divided by wavelength, l, or f = c/l.

In this case, f = (299,792,458 m/s)/(532 nm) = 564 THz, or 564 X 1012 Hz, or 564 X 1012 s-1, where m is meters, s is seconds, nm is nanometers = 10-9 m, Hz is Hertz = s-1, and THz is terahertz = 1012 Hz.

Answer 2

Frequency = (speed) / (wavelength) = (3 x 108) / (485 x 10-9) = 6.186 x 1014 =

6.186 x 105 GHz

= 618.6 THz

Answer 3

wlLet us use the relation, c = v l

here c - the velocity of electromagnetic wave in air (3 x 108 m/s)

v = the frequency in Hz

l = wavelength in m ( 575 * 10-9 m)

So v = c / l = 5.22 x 1014 Hz

Answer 4

Frequency of any wave = (wave speed) / (wavelength)

Frequency = (3 x 10^8 m/s) / (520 x 10^-9 m) =

5.769 x 10^14 per second =

5,769,231 GHz (rounded)

Answer 5

The fact that the light is green is not used in the calculation.Just divide the speed of light (3 x 10^8 meters/second) by the wavelength (converted to meters). The answer will be in hertz.
