A photon with a frequency of 5.48 × 10^14 hertz is emitted when an electron in a
mercury atom falls to a lower energy level.

Calculate the energy of this photon in joules. [Show all work, including the equation and substitution with
units.]

Respuesta :

     Using the Planck's Equation, comes:

[tex]E=hf \\ E=6.63*10^{-34}*5.48*10^{14}*J \\ \boxed {E=36.3324*10^{-20}*J}[/tex]

The energy of the photon in joules, given that it's has a frequency of 5.48×10¹⁴ Hz is 36.33×10¯²⁰ J

Data obtained from the question

  • Frequency (f) = 5.48×10¹⁴ Hz
  • Energy (E) =?

How to determine the energy

  • Planck's constant (h) = 6.63×10¯³⁴ Js
  • Frequency (f) = 5.48×10¹⁴ Hz
  • Energy (E) =?

The energy of the photon can be obtained as follow:

E = hf

E = 6.63×10¯³⁴ × 5.48×10¹⁴

E = 36.33×10¯²⁰ J
