Answer:
The Minimum wavelength is 
The Maximum wavelength is
Explanation:
From the question we are told that
The energy range is 
Considering 
When a single photon is transferred to to an electron the energy obtained can be calculated as follows

This energy is mathematically represented as

Here h is the Planck's constant with value of 
c is the speed of light with value of
Substituting values and making
