What is the wavelength of a 1400 kg truck traveling at a rate of 72 km/h?
Answered by DrBob222
Use the de Broglie equation,
wavelength = h/mv
mass in kg, v in m/s, h is Planck's constant.

What is the de Broglie wavelength of an electron (m = 9.11 10-31 kg) moving at a velocity of 3.0 107 m/s (10% of the speed of light)?
