de broglie equation is
wavelength ( ) = (h/mv)
1)
m =145 g = 0.145 Kg
v = 45 m/s
= (6.626×10-34/0.145×45)
or, =1.01×10-34 m.
2)
for electron
m =9.1×10-31 Kg
v =1.2×107 m/s
so, wavelength ( ) =(6.626×10-34/9.1×10-31×1.2×107)
or, wavelength () = 6.06×10-11 m .
3)
Wavelength of baseball is negligible.
but wavelength of electron is considerable ( within the range of atomic dimension) hence electron will behave like wave.

Learning Goal: To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light: λ=h/p, where λ is the wavelength, p the momentum, and h Planck's constant. Part...
