Acertain rifle bullet has a mass of 8.13 g. calculate the de broglie wavelength of the bullet traveling at 1337 miles per hour.

Mass of the bullet (m) = 8.13 g = 0.00813 kg

velocity of the bullet (v) = 1337 miles/hr

The de Broglie wavelength (∧) of an object of mass (m) travelling at a velocity (v) is given as:

∧ = h/m*v

where h = Planck's constant = 6.626 *10^-34 kgm2/s

Convert velocity from miles/hr to m/s

1 mile/hr = 0.447 m/s

1337 miles/hr = 0.447*1337 = 597.64 m/s

∧ = 6.626*10^-34 m2.Kg.s-1/0.00813 kg * 597.64 ms-1

∧ = 1.363*10^-34 m

Solution:

l dont know l am s sorry
