Question

What is the energy of a photon whose frequency is 5.0x10^14 hz

Answer 1

Energy of a photon is
`3.313* 10^(-19)\textrm{ J}`

Step-by-step explanation:

Given:

Frequency of the photon is,
`f=5.0* 10^(14)\textrm{ Hz}`.

Energy of a photon of frequency
`f` is given as:

`E=hf`, where,
`h` is called Planck's constant.

`h = 6.626* 10^(-34)\textrm{ J.s}`

So, energy of a photon is:

`E= 6.626* 10^(-34)* 5.0* 10^(14)=3.313* 10^(-19)\textrm{ J}`

Therefore, the energy of a photon whose frequency is
`5.0* 10^(14)` Hz is
`3.313* 10^(-19)\textrm{ J}`.
