Excited lithium ions emit radiation at a wavelength of 670.8 nm in the visible range spectrum. calculate the frequency of a photon of this radiation

Answer : The frequency of a photon of radiation is,

Explanation : Given,

Wavelength of the radiation = 670.8 nm

First we have to convert wavelength form 'nm' to 'm'.

Conversion used :

So, the wavelength of the radiation = 670.8 nm =

Now we have to calculate the frequency of a photon of radiation.

Formula used :

where,

= frequency of a photon of radiation

= wavelength of the radiation

c = speed of light =

Now put all the given values in the above formula, we get the frequency of a photon of radiation.

Therefore, the frequency of a photon of radiation is,

Explanation:

Hello,

In this case, we relate the speed of light, wavelength and frequency via the shown below equation expressed in the proper SI system of units:

Best regards.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
