Question

HELP? :D

An alpha particle (mass = 6.6 ✕ 10-24 g) emitted by radium travels at 3.2 ✕ 107 0.1 ✕ 107 mi/h. What is its de Broglie wavelength (in meters)?

Answer 1

Answer 2

de Broglie's equation is λ = h / p, where λ is the wavelength, p is the momentum of the particle (mass times velocity), and h is Planck's constant.

The plus minus thing is an uncertainty - that's how precise the measurement is. I don't know whether the problem requires that you calculate an uncertainty for your answer, but if so, you might try calculating the wavelength for 3.9 x 10^7 mph and seeing what the difference is. Yes Im a 14 year old geek but proud hope it helps

Answer 3

why would i do 3.9 when my problem is 3.2?
could you show me the steps so I can follow?
