An alpha particle has a mass of 6.6*1024 g travels at 3.4*107 +/ 0.1*107 mi/h
a. What is the DeBroglie wavelength (in meters)?
b. What is the uncertainty in position?

We Know that :
According to debroglies wavelength :
λ = h / mv
= 6.627 x 10 34 J s / 6.6 x1024 x 103 kg / 1 g x 3.4x 107 mile / hr x 5 793 638.4 m / s / 1 mile / hr
= 5.09 x 1022 m
