Question

An electron is moving with velocity $6.6\times {10}^{3}mls.$ The DE-Imbroglio wavelength associated with electron is $(massofelectron=9\times {10}^{-31}kg,$ Plank's Constant = $6.62\times {10}^{-34}J-S)$

• A. $1\times {10}^{-19}m$
• B. $1\times {10}^{-5}m$
• C. $1\times {10}^{-7}m$
• D. $1\times {10}^{-10}m$

Answer 1

The correct option is C $1\times {10}^{-7}m$

de broglie wavelength, $\lambda =\frac{h}{P}$

$\lambda =\frac{6.62\times {10}^{-34}}{g\times {10}^{-31}\times 6.6\times {10}^{3}m/s}$

$\lambda =1\times {10}^{-7}m$

Hence (C) option is correct
