Question

1 According to de-Broglie, matter should exhibit dual behaviour, that is both particle and wave like properties. However, a cricket ball of mass 100 g does not move like a wave when it is thrown by a bowler at a speed of 100 km/h. Calculate the wavelength of the ball and explain why it does not show wave nature? ​

Answer 1

λ=muh

=0.1kgx6.6×10−34

100km→3600sec

100×103m→3600sec

3600100×103←1sec

36103→1sec

361000−1sec

λ=1.0×5006.6×10−34×18

λ=5018×6.6×10−34

see the order of wavelength it is handly visible.

hope it helps you out
