3.98 x 10⁻¹⁹ Joule

Further explanation

Given:

The green light has a frequency of about 6.00 x 10¹⁴ s⁻¹.

Question:

The energy of a photon of green light (in joules).

The Process:

The energy of a photon is given by [tex]\boxed{\boxed{ \ E = hf \ }}[/tex]

  • E = energy in joules
  • h = Planck's constant 6.63 x 10⁻³⁴ Js
  • f = frequency of light in Hz (sometimes the symbol f is written as v)

Let us find out the energy of the green light emitted per photon.

[tex]\boxed{ \ E = (6.63 \times 10^{-34})(6.00 \times 10^{14}) \ }[/tex]

Thus, we get a result of [tex]\boxed{\boxed{ \ E = 3.98 \times 10^{-19} \ J \ }}[/tex]

Notes

  • When an electron moves between energy levels it must emit or absorb energy.  
  • The energy emitted or absorbed corresponds to the difference between the two allowed energy states, i.e., as packets of light called photons.  
  • A higher energy photon corresponds to a higher frequency (shorter wavelength) of light.

The energy of a photon of green light that has a frequency of 6.00×10¹⁴s−1 is 3.976 × 10-¹⁹J

HOW TO CALCULATE ENERGY:

  • The energy of a photon of light can be calculated by multiplying Planck's constant by the frequency of the photon:

E = hf

Where;

  1. E = energy of photon (Joules)
  2. h = Planck's constant (6.626 × 10-³⁴J)
  3. f = frequency of photon

  • According to this question, light has a frequency of about 6.00×10¹⁴s−1. The energy can be calculated as follows:

E = 6.626 × 10-³⁴ × 6.00×10¹⁴

E = 39.76 × 10-³⁴+¹⁴

E = 39.76 × 10-²⁰

E = 3.976 × 10-¹⁹J

  • Therefore, the energy of a photon of green light that has a frequency of 6.00×10¹⁴s−1 is 3.976 × 10-¹⁹J.
