Question

calculate the wavelength of moving particle whose mass and
velocity are 1mg and 3600km/h

Kumar Sarang · Accepted Answer

Mass = 1 mg = 1 x 10-6 Kg
Velocity = 3600 Km/h = (3600 x 1000)/3600 m/s = 1000 m/s
Planck's constant h = 6 626 x 10-34 Js

De broglie relation -
Wavelength = λ =
h/p
Wavelength = λ =
h/(mv)
Wavelength = h/(mv)

= 6 626 x 10-34/(10-6 x 1000) m
= 6 626 x 10-31 m Answer

Note- p-momentum
