Vedclass · Answer

(A) The de Broglie wavelength is given by the formula: $\lambda = \frac{h}{mv}$ Given: $h = 6.626 	imes 10^{-34} \ J \cdot s$ $m = 66 \ g = 66 	imes 10^{-3} \ kg = 6.6 	imes 10^{-2} \ kg$ $v = 10 \ m/s$ Substituting the values: $\lambda = \frac{6.626 	imes 10^{-34}}{6.6 	imes 10^{-2} 	imes 10} \ m$ $\lambda \approx \frac{6.626 	imes 10^{-34}}{6.6 	imes 10^{-1}} \ m$ $\lambda \approx 1.004 	imes 10^{-33} \ m$ Thus,the value is approximately $10^{-33} \ m$.
