De Broglie Wavelength and Wave Nature of a Bullet: Explanation and Significance

[abrowaqas]

This question appeared in my exam .

Q. A bullet of mass 41g travels at 960m/s. what wavelength can we associate with it?
why does the wave nature of the bullet not reveal itself though diffraction effects?

Ans..

i find de broglie wave length by formula

lamda = h/mc

but didnt able to give answer of the WHY question?

somebody help what does it mean?

Why? Just because the wavelength is so small that diffraction effects are negligible. By the way, you've got the two wavelengths confused. h/mc is the Compton wavelength. The be Broglie wavelength is h/mv.

thanks bill k..
yes i put the h/mv..

but written wrong reason there..
