SUMMARY

The discussion focuses on calculating the energy of a neutron with a wavelength of 0.1 nm using the equation E = hv/L. Participants explore the relationship between energy, wavelength, and momentum, specifically addressing the conversion of wavelength to energy through the de Broglie wavelength formula, λ = h/p. The conversation clarifies that total energy includes both kinetic energy and rest energy, prompting users to consider how to incorporate these components into their calculations.

PREREQUISITES
  • Understanding of quantum mechanics principles, specifically wave-particle duality.
  • Familiarity with the de Broglie wavelength formula, λ = h/p.
  • Knowledge of energy equations, including E = hv and the relationship between kinetic and rest energy.
  • Basic grasp of neutron properties and their significance in physics.
NEXT STEPS
  • Study the de Broglie wavelength and its implications in quantum mechanics.
  • Learn about the relationship between kinetic energy and total energy in particle physics.
  • Explore the concept of rest energy using Einstein's equation, E = mc².
  • Investigate practical applications of neutron wavelengths in experimental physics.
USEFUL FOR

Students in physics, particularly those studying quantum mechanics and particle physics, as well as educators seeking to clarify concepts related to energy calculations in wave-particle duality.

Calculate the energy of a neutron wavelength 0.1nm


Homework Equations





The Attempt at a Solution



let L = lambda

So i just use E = hv/L

L = hv/E

But how do i write v in terms of E? isn't E the total energy rather than just kinetic...
 
Physics news on Phys.org
Or can i use lambda = h/p, work out the KE, then add on the rest energy?
