The de Broglie equation describes the relationship between the wavelength associated with the motion of an electron and its:

The velocity associated with a proton moving in a potential difference of $1000 \, V$ is $4.37 \times 10^{5} \, ms^{-1}$. If a hockey ball of mass $0.1 \, kg$ is moving with this velocity,calculate the wavelength associated with this velocity.

What will be the wavelength of a ball of mass $0.1 \,kg$ moving with a velocity of $10 \,m \,s^{-1}?$

The wavelength associated with the motion of an electron:

The wavelength (in $m$) of a particle of mass $11.043 \times 10^{-26} \ kg$ moving with a velocity of $6.0 \times 10^7 \ ms^{-1}$ is $.......$

If the kinetic energy of a particle is increased to $4$ times its initial value,how many times will the associated de Broglie wavelength become?
