Question

A certain shade of blue has a frequency of 7.26 × 1014 Hz. What is the energy of exactly one photon of this light?

Answer 1

7.20 it the energy because


10\7.26 is 7.20
- 70

Answer 2

Energy of one photon =
`4.81* 10^(-19)J`

Step-by-step explanation:

Frequency =
`7.26* 10^(14)\ Hz`

Energy of a photon is given by:

E = hν

Where,

h = Plank's constant

ν = Frequency

h =
`6.626* 10^(-34)J\ s`

ν =
`7.26* 10^(14)\ Hz\ or\ 7.26* 10^(14)\ s^(-1)`

E = hν

`=(6.626* 10^(-34)Js)* (7.26* 10^(14)\ s^(-1))\\=4.81* 10^(-19)J`

Energy of one photon =
`4.81* 10^(-19)J`
