    The energy of the photon can be calculated using one of the following two rules:

    Rule 1: E = hf where h is Planck's constant and f is the frequency

    Rule 2: E = (hc) / lambda where h is Planck's constant, c is the speed of light and lambda is the wavelength.

    We are given that:

    Planck's constant (h) = 6.63 * 10^-34 Js

    frequency (f) = 7.3 * 10^-17 Hz

    Based on these givens, we will use Rule 1.

    Substitute with the givens in Rule 1 to get the energy as follows:

    E = hf

    E = 6.63 * 10^-34 * 7.3 * 10^-17

    E = 4.8 * 10^-50 Joules
