The resolving power of a microscope depends
on the wavelength of the photon used to examine the object that is observed.
What is the energy of the photons that
must be used to resolve a molecule whose
size is 0.82 nm? The value of h c is
1.98 × 10
−25
J · m.
Answer in units of eV

E = hc / wL

where 'wL' is the photon's wavelength

c = (f) x (wL)

where 'c' = 3.0 x 10^8 m/sec.

f = frequency in Hz.
