Question

What is the energy of a photon of violet light with a frequency of 7.79*
`10^(14)`
`s^(-1)`? (answer in joules)

Answer 1

`E=5.16* 10^(-19)\ J`

Step-by-step explanation:

Given that,

The frequency of violet light,
`f=7.79* 10^(14)\ Hz`

We need to find the energy of a photon. The formula for the energy of a photon is given by :

`E=hf\\\\E=6.63* 10^(-34)* 7.79* 10^(14)\\\\E=5.16* 10^(-19)\ J`

So, the energy of a photon is equal to
`5.16* 10^(-19)\ J`.
