Energy of photon is equal to the product of Planck's constant and frequency.

The mathematical expression is given as :

$E = h\\u$

where,

E = energy of photon

h = Planck's constant i.e.
6.626 * 10^(-34) Js

$\\u$ = frequency

Put the given values of frequency and Planck's constant in above formula, we get

E =6.626 * 10^(-34) Js* 7.05 * 10^(14) Hz

=
46.7133* 10^(-20) Js Hz

Since, Hz is equal to
second^(-1)

Thus, energy of photon =
or
