Calculate the de broglie wavelength of a shotgun
pelletweighing 1.2 g moving at a velocity of 150 m/s.

Answer : The de Broglie wavelength will be

Solution :

The formula used for de Broglie wavelength is:

..........(1)

where,

= wavelength  = ?

h = Planck's constant  =

m = mass  = 1.2 g = 0.0012 kg

Conversion used : 1 kg = 1000 g

v = velocity  = 150 m/s

Now put all the given values in equation 1, we get:

Therefore, the de Broglie wavelength will be
