Answer 2

Calculating Photon Energy in Joules

To calculate the energy of a photon in joules, we can use the formula:

E = hf

Where: - E = energy of the photon in joules - h = Planck's constant (6.626 x 10^-34 J·s) - f = frequency of the photon in hertz

Given that the energy of the photon in electron volts (eV) is 7 eV, we can convert this to joules using the relationship:

1 eV = 1.602 x 10^-19 J

So, the energy of the photon in joules can be calculated as:

E = 7 eV * (1.602 x 10^-19 J/eV)

Let's calculate the energy of the photon in joules.
