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).(adsbygoogle = window.adsbygoogle || []).push({});

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 (5.9742x10^{24}kg * (approx) 3x10^{4}m/s).

So... 6.626x10^{-34}/(5.9742x10^{24}kg * (approx) 3x10^{4}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).
