quanta to quarks question (1 Viewer)

[scarvesss]

if you have jacaranda hsc its q8 on page 452.

if not:

a neutron emitted when a uranium-235 nucleus undergoes fission may have an energy of about 1 MeV. a Thermal neutron that would be captured by uranium 235 nucleus in a nuclear reactor would have an energy of about 0.02 MeV

(a) calculate the wavelength of a 1MeV neutron
(b) calculate the wavelength of 0.02MeV neutron

can someone help me out with this, im lost.

I'll give you a hint.
Use E=1/2 mv^2
and de broglie's wavelength equation
