So I was reading about De Broglie's theory of particle-wave duality the other day and I came across the equation: λ=h/p. I expect most of you are familiar with this equation but if you're not, it is: wavelength = Planck's length over momentum (mass x velocity).
So I thought i'd try and find the Earth's wavelength.
So first I found out what I would have to do to find p, which is (5.9742x1024kg * (approx) 3x104 m/s).
So... 6.626x10-34/(5.9742x1024kg * (approx) 3x104 m/s)
This is equal to... 3.697×10^-63 meters.
When I first saw that, I was mind blown. Will someone explain why it's wavelength is that small?
Thanks, Ben - I'm unsure of this because well, I'm quite young (15).
