Are you looking for an answer to the topic “How do you find the de Broglie wavelength of an electron from kinetic energy?“? We answer all your questions at the website Chiangmaiplaces.net in category: +100 Marketing Blog Post Topics & Ideas. You will find the answer right below.
If you double the kinetic energy of a particle, how does the deBroglie wavelength change? Solution: λ = h/p, E = p2/(2m), p is proportional to √E, l is proportional to 1/√E. λ2/λ1 = √(E1/E2) = 1/√2.De-Broglie wavelength of a particle is inversely proportional to the momentum of that particular body. We should know that kinetic energy and momentum of a particle is related as. E=P22m.Equation Number Two: λ = h/p
it is here in case you migt be interested in it. Suppose an electron has momentum equal to p, then its wavelength is λ = h/p and its frequency is f = E/h.
