# Problem: A 0.22 caliber handgun fires a 29 g bullet at a velocity of 775 m/s.a. Calculate the de Broglie wavelength of the bullet.b. Is the wave nature of matter significant for bullets?

###### FREE Expert Solution

We’re asked to a) calculate the de Broglie wavelength of a 29 g bullet at a velocity of 775 m/s and to b) determine if the wave nature of matter is significant for the bullet.

Recall that the de Broglie wavelength (λ) can be calculated using:

$\overline{){\mathbf{\lambda }}{\mathbf{=}}\frac{\mathbf{h}}{\mathbf{mv}}}$

where:

h = Planck's constant (6.626 × 10–34 kg • m2/s)

m = mass (in kg)

v = velocity (in m/s)
