We, Know for any electromagnetic wave(or light)
c=f*l
where,
c=speed of that wave(or light)=3*10^8 m/s
f=frequency of the wave
l=wavelength of the wave
for the given case, l=600 nm=6*10^-7 m
So, Frequence f=c/l=5*10^14 Hz

∙ 14y agoAll light travels in the speed of light in vacuum, that is 300,000 km/sec. The relevant formula is C = f*lambda, where C is the speed of light, f is the frequency and lambda the wavelength. Therfore, f = C/lambda. Here lambda = 632.8nm, so f = 4.741E14 or 474 terahertz.
The color of this light, incidentally, is red. Please see the links. They are beautiful, anyway.

∙ 11y ago"The frequency of an atom" is a rather blurry concept. We'll be much better off
if we simply concentrate our attention on the photon.
Frequency = speed/wavelength = 300,000,000/265 x 10-9 = 1.13 x 1015 Hz

∙ 6y agoConvert that to meters. Then divide the speed of light (in meters/second) by the wavelength. The answer will be in hertz.

A strong line in the spectrum of atomic mercury has a wavelength of 254 nm When mercury emits a photon of light at this wavelength the frequency of this light is?
254 nm= 254 x 10-9 m C=λv 3.00 x 108 m/s= 254 x 10-9 m (v) v= 1.18 x 1015 Hz
Determine the end value of n in a hydrogen atom transition if the electron starts in n equals 4 and the atom emits a photon of light with a wavelength of 486nm?
The end value of "n" is 2.
Whenever an excited hydrogen atom falls back from an excited state to its ground state it?
The answer is (B) Emits a Photon of Radiation.
What happens when the electrons return from the excited state to the ground state?
it looses energy , it gives off light in the form of a single photon.
When an electron in H changes it's spin from the same to the opposite direction as the proton?
emits radio wave photon.
How does the frequency of radiant energy relate to the absolute temperature of the radiating source?
A low temp source emits low-frequency, long wavelength waves. A medium temp source emits medium frequency, medium wavelength waves. A high temp source emits high frequency, short wavelength waves.
A helium neon laser emits light of wavelength 633 nm Light from an argon laser has a wavelength of 515 nm Which laser emits the higher frequency light?
according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..

What is the difference between linear and non linear optics?
In the case of linear optical transitions, an electron absorbs a photon from the incoming light and makes a transition to the next higher unoccupied allowed state. When this electron relaxes it emits a photon of frequency less than or equal to the frequency of the incident light (Figure 1.3a). SHG on the other hand is a two-photon process where this excited electron absorbs another photon of same frequency and makes a transition to reach another allowed state at higher energy. This electron when falling back to its original 39 state emits a photon of a frequency which is two times that of the incident light (Figure 1.3b). This results in the frequency doubling in the output.
