Vedclass · Answer

(A) The de Broglie wavelength $\lambda$ is given by the formula $\lambda = \frac{h}{mv}$.Given: $m = 25 \, g$,$v = 6.6 	imes 10^4 \, cm/sec$,$h = 6.626 	imes 10^{-27} \, erg \cdot sec$ (in $CGS$ units).Substituting the values:$\lambda = \frac{6.626 	imes 10^{-27} \, erg \cdot sec}{25 \, g 	imes 6.6 	imes 10^4 \, cm/sec}$$\lambda \approx \frac{6.6 	imes 10^{-27}}{25 	imes 6.6 	imes 10^4} \, cm$$\lambda \approx \frac{10^{-27}}{25 	imes 10^4} \, cm$$\lambda \approx 0.04 	imes 10^{-31} \, cm = 4 	imes 10^{-33} \, cm$.

$A$ ball weighing $25 \, g$ moves with a velocity of $6.6 \times 10^4 \, cm/sec$. The de Broglie wavelength associated with it is .....
