What is the energy range (in ev) of photons of wavelength 410 nm to 750 nm ? express your answers using two significant figures separated by a comma.

Explanation:

It is given that,

Wavelength 1,

Wavelength 2,

Energy of a photon having wavelength 1 is given by :

Energy of a photon having wavelength 2 is given by :

Hence, this is the required solution.
