using, lemda = h/mv, we have

1) for electron

lemda e =

6.6× 10^-34/9.1×10^-31×1/100×3×10^8

=2.4×10^-10m

= 2.4 A

2) for ball,

lemda b = 6.6× 10^-34/3× 10^-2×100

= 2.2×10^-34

since wavelength of the moving ball is very very small which cannot be detected Thursday wave nature of matter is not really relevant at the macroscopic level .
