Question

2. Ultraviolet radiation has a frequency of 6.8 x 10'5Hz. Calculate the energy, in

joules, of the photon.

Answer 1

`E=4.5* 10^(-18)\ J`

Step-by-step explanation:

It is given that, the frequency of Ultraviolet radiation is
`6.8* 10^(15)\ Hz`

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

`E=hf\\\\\text{Where h is Planck's constant}\\\\E=6.63* 10^(-34)* 6.8* 10^(15)\\\\E=4.5* 10^(-18)\ J`

So, the energy of the photon is
`4.5* 10^(-18)\ J`.
