This guy was a genius in my view. His equation is the most beautiful in all of Physics (everyone else can disagree, they are simply wrong!)

#### Explanation:

The equation is $\lambda = \frac{h}{p}$ where p is momentum and h is Planck’s constant.

OK, so $p = m \times v = 9.11 \times {10}^{-} 31 k g \times 1.33 \times {10}^{5} \frac{m}{s}$

Which gives us $p = 1.21 \times {10}^{-} 25 N s$

Taking $h = 6.63 \times {10}^{-} 34$ Js, I get the wavelength to be $5.47 \times {10}^{-} 9$ m
