Question
An electron volt, eV, is, in many cases, a more convenient unit of energy to
use to describe atomic and molecular phenomena compared to joules.
The human eye, for example, can be thought of as a photodetector
sensitive to photons with an energy of 2 to 3 electron volts. If a human
eye detects colors that have 2.35 eV of energy, what wavelength, in nm,
does it have?
Hint: 1 eV 1.602x10 19 J (exact)
