What is the energy content per photon?
Photons are electrically neutral. Photons have no mass, but they have energy E = hf = hc/λ. Here h = 6.626*10-34 Js is a universal constant called Planck’s constant. The energy of each photon is inversely proportional to the wavelength of the associated EM wave.
What is the energy content per?
Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g).
How do you find the minimum energy of a photon?
Therefore, the minimum energy of each photon, hfmin is given by equating the energy of the two photons, 2hfmin, to the rest energy of the positron and of the electron (i.e. 2hfmin = 2E0, where E0 is the rest energy of the electron.)
How much energy is needed for pair production?
Because an electron has a rest mass equivalent to 0.511 MeV of energy, a minimum gamma-energy of 1.02 MeV is required for this pair production. Any excess energy of the pair-producing gamma-ray is given to the electron–positron pair as kinetic energy.
What is the frequency of red light 650 nm in a vacuum?
Red light has a wavelength of ~700 nm, and a frequency of ~4.3*1014 Hz.
What is the frequency of a 650 nm wavelength?
4.62 1014 Hz
What is the frequency of light with wavelength of 600 nm?
2 = 600 nm = 600 x 10-7cm=6 x 10 cm c=3 x 100 cm/sec 3 x 1010 = 0.5 x 10 sec (or) 5×10’4 sec -! 26XIO.
What is the frequency of red light with a wavelength of 700 nm?
Visible red light with a wavelength of 700 nm, for example, has a frequency of 4.29 x 1014 Hz, and an energy of 40.9 kcal per mole of photons. The full range of electromagnetic radiation wavelengths is referred to as the electromagnetic spectrum.
Which electromagnetic wave can travel the farthest distances because it has a wavelength range?
Radio waves
Which compound has the highest frequency lowest frequency?
Answer: Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
What letter shows the shortest wavelength Brainly?
Answer. Answer: Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
What would happen if wave frequency is increased?
1. If the frequency of a wave is increased, what happens to its wavelength? As the frequency increases, the wavelength decreases.
