A 0.22 caliber handgun fires a 1.9g bullet at a velocity of 765m/s. Calculate the de Broglie wavelength of the bullet. Is the wave nature of matter significant for the bullets?

Explanation:

Given;

mass of the bullet, m = 1.9 g = 0.0019 kg

velocity of the bullet, v = 765 m/s

de Broglie wavelength of the bullet is given by;

where;

h is Planck's constant = 6.626 x 10⁻³⁴ J/s

λ is de Broglie wavelength of the bullet

Thus, this value of the wavelength shows that wave nature of matter is insignificant for the bullet because it is larger than particles.

like poles repel so keep pushing north to north and repels funny to see this

i had this question and the answer was 3.15 miles.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles
