The energy of a 500 nm photon is 3.1 eV (electron volts). This is a unit of measure used to represent the energy of a single photon. To put this into perspective, a single photon of visible light has an energy of 1.8 to 3.1 eV, and a single photon of ultraviolet light has an energy of 3.1 to 124 eV.

The energy of a 500 nm photon can be calculated by using the following equation:

  • E = hc/
  • Where:
    • E = energy of the photon (in eV)
    • h = Planck's constant (6.626 * 10-34 Js)
    • c = speed of light (2.998 * 108 m/s)
    • = wavelength of photon (in meters)

Therefore, the energy of a 500 nm photon is calculated as follows:

  1. Convert the wavelength from nanometers to meters: 500 nm = 0.0005 m
  2. Insert the values into the equation: E = (6.626 * 10-34 Js) * (2.998 * 108 m/s) / (0.0005 m)
  3. Calculate the energy: E = 3.1 eV

Therefore, the energy of a 500 nm photon is 3.1 eV.

When an electron in atom changes energy states a photon is emitted If the photon has a wavelength of 550 nm how did the energy of the electron change?

The energy of the electron decreased as it moved to a lower energy state, emitting a photon with a wavelength of 550 nm. This decrease in energy corresponds to the difference in energy levels between the initial and final states of the electron transition. The energy of the photon is inversely proportional to its wavelength, so a longer wavelength photon corresponds to lower energy.

To determine the energy of a photon of orange light with a wavelength of 600 nm, we can use the formula E = hc/λ, where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength in meters. Converting the wavelength to meters (600 nm = 600 x 10^-9 m), we can plug the values into the formula to find the energy of the photon. The energy of a photon of orange light with a wavelength of 600 nm is approximately 3.31 x 10^-19 joules.
