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)?

a 1132eV bThe equation for a photons energy can be written E hc where h is known as Plancks constant and is equal to 4136 1015 eV s Note that h has a different class=
