a) 1.132eV
b)The equation for a photon's energy can be written:
E =
hc
where h is known as Planck's constant and is equal to 4.136 ✕ 10−15 eV · s. (Note that h has a different numerical value in SI units.)
Since we know that for light
c
= f,
we can rewrite the equation for the energy of a photon as E = h · f.
What, then, is the frequency (in Hz) of the photon from your answer to part (a)?
