Question

the de brglie wave length of a boll of mass 10g moving with velocity of 10ms^_1 is (h=6.625×10^_34


​

Answer 1

$\text{De broglie wavelength is given by }\lambda = \cfrac{h}{p} = \cfrac{h}{mv}$

$\therefore \lambda = \cfrac{6.625 \times 10^{-34}}{\cfrac{10}{1000}\times10}$

$\therefore \lambda = 6.625 \times 10^{-33}$
