What is the wavelength of a 1400 kg truck traveling at a rate of 72 km/h?

Answer 1

Use the de Broglie equation,
wavelength = h/mv
mass in kg, v in m/s, h is Planck's constant.

Answer 2

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)?

Answer 3

14?

Answer 4

Thank you so much DrBob222!!! You really saved my day on this last minute assignment turn-in. I don't know if you'll ever see this, but your explanations and help and contributions have been noticed and we are all grateful for this.
