The de-Broglie wavelength associated with a material particle is

What is the de Broglie wavelength of a tennis ball weighing $66 \ g$ moving with a velocity of $10 \ m/s$?

According to the wave-particle duality of matter by de-Broglie,which of the following graph plots presents the most appropriate relationship between the wavelength of an electron $(\lambda)$ and the momentum of an electron $(p)$?

The velocities of two particles $A$ and $B$ are $0.05 \ ms^{-1}$ and $0.02 \ ms^{-1}$ respectively. The mass of $B$ is five times the mass of $A$. The ratio of their de-Broglie's wavelength is

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.

$A$ moving particle may have significant wave motion,if
