Question

A photon of blue light has a wavelength of 4.62 x 10m (462 nm). Calculate the energy of this photon

Answer 1

`E=4.3* 10^(-19)\ J`

Step-by-step explanation:

Given that,

The wavelength of a photon of blue light is 462 nm

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

`E=(hc)/(\lambda)\\\\E=(6.63* 10^(-34)* 3* 10^8)/(462* 10^(-9))\\\\=4.3* 10^(-19)\ J`

So, the energy of this photon is
`4.3* 10^(-19)\ J`.
