Question

Calculate the energy per photon (in J) associated with a frequency of 1260 kHz. Submit answer in scientific notation using the format 0.00 x 10^0 (e.g. 0.000123 = 1.23 x 10^-4). Omit units and spaces.

Answer 1

Taking into account the definition of photon and energy of a photon, the energy per photon is 8.3538×10⁻³⁸ J.

Energy of a photon

Electromagnetic radiation carries energy, which can be absorbed or emitted. To explain the processes of emission and absortion, Plank and Einstein proposed that the energy of radiation is composed of indivisible units (quanta). In each elemental process only a quantum of light can be emitted or absorbed. Each of these quanta was called a "photon".

The exchanges of energy between matter and radiation take place not continuously, but by discrete and indivisible quantities or quanta of energy. The quantum of energy is proportional to the frequency of radiation.

The relationship between the amount of energy (E) transported by the photon and its frequency (f) is determined by the following expression:

E=h×f

where:

• E is the energy of a photon.
• h is the Planck's constant h.
• f is the frequency of electromagnetic radiation.

Energy per photon

In this case, you know:

• h=  6.63*10⁻³⁴ Js
• f= 1260 kHz= 1,260,000 Hz= 1.26×10⁶ Hz (being 1 kHz=1000 Hz)

Replacing in the definition of energy of a photon:

E= 1.26×10⁶ Hz× 6.63×10⁻³⁴ Js

E= 8.3538×10⁻³⁸ J

Finally, the energy per photon is 8.3538×10⁻³⁸ J.
