Question

The blue colour of the sky results from the scattering of sunlight by air molecules. Blue light has a frequency if about 7.5*10^14Hz

Calculate the energy of a mole of photon associated with this frequency

Answer 1

Answer: The energy of a mole of photon associated with this frequency is
`49.5* 10^(-20)J`

Step-by-step explanation:

The energy and frequency are related by :

`E=N* h* \\u`

E = energy of photon

N = number of moles = 1

h = planks constant =
`6.6* 10^(-34)Js`

`\\u` = frequency =
`7.5* 10^(14)Hz`

`E=1* 6.6* 10^(-34)Js* 7.5* 10^(14)s^(-1)=49.5* 10^(-20)J`

The energy of a mole of photon associated with this frequency is
`49.5* 10^(-20)J`
