An atom emits a photon with energy 7.13 electronvolts (eV). What is the wavelength of the photon? a. 279 nm
b. 174 nm
c. 114 nm
d. 108 nm

Option (b) "174 nm"

Explanation:

Energy of emitted photon is 7.13 eV.

We need to find the wavelength of the photon.

1 eV = 1.6 × 10⁻¹⁹ J

Energy of a photon is given by :

Where, is wavelength of the photon

Putting all the values,

So, the wavelength of the photon is 174 nm.

you gotta add the following molecules so we can give u an answer
