Consider a beam of electron directed towards a crystal if the crystal spacing is ' $b$ ', the deBroglie wavelength for which the electron beam will be reflected back along the same path $\mathrm{n}$ being an integer is
1 $\frac{2 b}{n}$
2 $2 \mathrm{bn}$
3 $\frac{\mathrm{b}}{2 \mathrm{n}}$
4 $b^{2} n$
Explanation:
A $\lambda=\frac{2 b}{\mathrm{n}}$

Which phenomenon best supports the theory that matter has a wave nature?
1 electron momentum
2 Electron diffraction
3 Photon momentum
4 Photon diffraction
Explanation:
B Davisson and Germen (1923) proved that matter has a wave nature. The experiment was based on electron diffraction.
