The de-Broglie hypothesis predicts that a wave associated with any object has momentum. Why do we not observe the wave nature of a moving car?

Why we do not see the wave properties of a baseball ?

According to De-Broglie, the waves are associated with

Why is de Broglie wave termed as matter wave?

According to de Broglie, what is the relation between the wave length of the wave associated with the moving electron and momentum of the f electron?
