The line spectrum of lithium has a red line at 670.8 nm. calculate the energy of a photon with this wavelength.

The energy of the photon having the given wavelength is

Explanation:

We are given:

Wavelength of microwave =    (Conversion factor:    )

To calculate the energy of one photon, we use Planck's equation, which is:

where,

h = Planck's constant =

c = speed of light =

= wavelength =

Putting values in above equation, we get:

Hence, the energy of the photon having the given wavelength is

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.
