Question #330157

When light from a red laser, with a wavelength of 632 nm, is incident on a certain double slit, a particular interference pattern is observed. The laser light is replaced by a beam of electrons, all with the same energy, and exactly the same interference pattern is observed. What is (a) the wavelength, (b) frequency, and (c) energy of the electrons?

a)

λ=632 nm,\lambda=632~nm,

b)

ν=cλ=4.71014 Hz,\nu=\frac c\lambda=4.7\cdot 10^{14}~Hz,

c)

E=hν=3.11019 J.E=h\nu=3.1\cdot 10^{-19}~J.
