Answer:
1.82x10⁻¹⁹Joules is the energy of the photon that is absorbed by the electron.
Step-by-step explanation:
The energy of a photon is given by the equation:
E = h×ν
Where E is energy of the photon in Joules.
h is Planck's constant (6.6262x10⁻³⁴Js)
And ν is frequency of the photon (In Hz = s⁻¹)
The frequency of the photon is 2.74x10¹⁴Hz. That means its energy is:
E = 6.6262x10⁻³⁴Js × 2.74x10¹⁴s⁻¹
E =
1.82x10⁻¹⁹Joules is the energy of the photon that is absorbed by the electron
