What is the formula for De Broglie's wavelength
wavelength = planck's constant/(mass*velocity)
wavelength = planck's constant/(momentum/velocity)
wavelength = planck's constant*(momentum*velocity)
E = hf
What is the evidence for constructive interference?
Bright and dark fringes in Diffraction
Bright fringes in reflection
Total internal reflection
When electrons are accelerated in a ( (a) ) and are passed through a screen, diffraction patterns can be observed.
What was the experimental outcome of Davisson-Germer's experiment?
165 m
167 nm

167 m
What is diffraction?
Diffraction is the spreading of waves around obstacles.
Diffraction takes place with sound and with electromagnetic radiation, such as light, X-rays, and gamma rays.
Diffraction takes place with electrons, which show wavelike properties.
Diffraction is a hoax
