The energy of a photon is:

#E = hf#

Where #h# is Planck's Constant and #f# is the frequency (in Hertz).

Given #f = 100MHz#

Convert the frequency to Hertz:

#f = 1.00xx10^8Hz#

NOTE: An alternative unit for #Hz# is #s^-1#

Using the value for Planck's Constant, #h=6.626xx10^-34J*s#:

#E = 6.626xx10^-34J*s(1.00xx10^8s^-1)#

#E = 6.626xx10^-26J#
