Answer 1

Solution:

$(i) \: λ_{e} = \frac{h}{ m_{e} v_{e} } \\ = \frac{6.63 \times {10}^{ - 34} }{9.11 \times {10}^{ - 31} \times 5.4 \times {10}^{6} } \\ \\ = 0.135 \times {10}^{ - 9} m = 0.135nm \\ \\ (ii) \: λ_{b} = \frac{h}{ m_{b} v_{b} } \\ \\ = \frac{6.63 \times {10}^{ - 34} }{0.150 \times 30.0} \\ \\ = 1.47 \times {10}^{ - 34} m$
