How the frequency of the emitted photon is related to energy difference?
The amount of energy is directly proportional to the photon’s electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon’s frequency, the higher its energy. Equivalently, the longer the photon’s wavelength, the lower its energy.
Does higher energy mean higher absorbance?
Absorption is shown by the energy levels increasing as the photon gains energy. The wavelengths shown relate to the amount of energy in the photon. Notice how the emitted light wavelengths are shorter than the absorbed light wavelengths.
In which part of the electromagnetic spectrum does a photon have the greatest energy?
Gamma rays
Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
What is the energy in joules of a photon of light having a frequency of a typical radio wave?
The answer is 3.54×10−19 J . The equation for determining the energy of a photon of electromagnetic radiation is E=hν , where E is energy in Joules, h is Planck’s constant, 6.626×10−34J⋅s , and ν (pronounced “noo”) is the frequency.
What happens to the frequency when the energy of a photon increases?
An increase in frequency produces a proportional decrease in the wavelength of light with a corresponding increase in the energy of the photons that make up the light. Upon entering a new medium (such as glass or water), the speed and wavelength of light is reduced, although the frequency remains unaltered.
Which of the following has the highest photon energy?
gamma rays
The photon energy of gamma rays can be considered to be the highest energy since it has the highest frequency in the electromagnetic spectrum.
