An alpha particle has a mass of 6.6*10-24 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?

  • chemistry -

    We Know that :
    According to debroglies wavelength :
    λ = h / mv
    = 6.627 x 10 -34 J -s / 6.6 x10-24 x 10-3 kg / 1 g x 3.4x 107 mile / hr x 5 793 638.4 m / s / 1 mile / hr
    = 5.09 x 10-22 m
