The einstein is a unit defined as the energy in one mole of photons (6.022×1023 photons). Because energy is inversely proportional to wavelength, the unit is frequency dependent. In studies of photosynthesis the einstein is sometimes used with a different definition of one mole of photons.
How do you find energy in kJ mol?
A slightly different way would be to use Eλ = hc (with the wavelength in meters) and solve for E, then multiply the answer times Avogadro’s Number. Finally, divide by 1000 to get kJ/mol. Example #3: How many kJ/mol (remember: mol means mole of photons) of energy is contained in light with a wavelength of 496.36 nm?
What happens when 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. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa.
What is Photon made up of?
A photon is a tiny particle that comprises waves of electromagnetic radiation. As shown by Maxwell, photons are just electric fields traveling through space. Photons have no charge, no resting mass, and travel at the speed of light.
How does photon look like?
A photon just looks like a blink of light from a small point. So, when you see a photon (if your eyes are sensitive enough), you see a blip of light. The “size” of a photon is much weirder since photons aren’t “particles” in the traditional macroscopic sense of the word.
Does a photon have rest energy?
Since photons have zero rest mass then their energy is simply E = pc. The fact that light carries momentum is also verified by experiment.
What is the color of healing energy?
At the other end of the color spectrum, red light has been shown to be effective in the treatment of cancer and constipation and in healing wounds. As a result, color is becoming widely accepted as a therapeutic tool with various medical applications.
