What is the de Broglie wavelength of a. a bullet of mass 0.040 kg travelling at the speed of 1.0 km/s, b. a ball of mass 0.060 kg moving at a speed of 1.0 m/s, and c. a dust particle of mass 1.0xx10^(-9) kg drifting with a speed of 2.2 m/s ? |

Answer» SOLUTION :`m=0.04kg, v=1xx10^(3)ms^(-1)` a.`LAMBDA=(h)/(mv)=(6.6xx10^(-34))/(0.04xx10^(3))=1.65xx10^(-35)m` b. `lambda=(h)/(mv)=(6.6xx10^(-34))/(0.06xx1)=1.1xx10^(-32)m` c. `lambda=(h)/(mv)=(6.6xx10^(-34))/(1xx10^(-9)xx2.2)=3xx10^(-23)m ` |
