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
