Q&A: What is the energy of a photon that has the same wavelength as an electron with energy 1.60e-15 J?
Oct 15th
Question by eventer02: What is the energy of a photon that has the same wavelength as an electron with energy 1.60e-15 J? What is the energy of a photon that has the same wavelength as an electron with energy 1.60e-15 J? if i needed the answer in keV how would i convert it?
Best answer:
Answer by kirchweyI assume the electron energy is kinetic energy. Using the relativistic DeBroglie solution (ref.), lambda(e) = 1.2213073E-11 m Photon energy = hc/lambda = 1.6264911E-14 J EDIT: You added question: To convert to eV divide by the elementary charge 1.6022E-19 C/e.

Q&A: What is the energy of a single UV photon having a wavelength of 33 nm?
Sep 5th
Question by nolifegurl: What is the energy of a single UV photon having a wavelength of 33 nm? a) A photon of ultraviolet (UV) light possesses enough energy to mutate a strand of human DNA. What is the energy of a single UV photon having a wavelength of 33 nm?
b) What is the energy of a mole of UV photons having a wavelength of 33 nm?
Best answer:
Answer by Borona) the energy of a photon is given by the equation E = hf where h is Planck’s constant (6.626E-34 Js) and f is the frequency of the photon. Since you have More >
What is the energy of a mole of UV photons having a wavelength of 39 nm?
Sep 2nd
Question by s: What is the energy of a mole of UV photons having a wavelength of 39 nm? A photon of ultraviolet (UV) light possesses enough energy to mutate a strand of human DNA. What is the energy of a single UV photon having a wavelength of 39 nm? 5.1e-18 J
that was the first question…but then it asks: What is the energy of a mole of UV photons having a wavelength of 39 nm? -the answer is in Joules
please explain it!
