λ = h / MV
MV = h / λV
-----------------------------
------------------------------------------------
M --- mass of proton
h --- planck's constant
λ --- Wave length
V --- Velocity
--------------------------------
--------------------------------------------------
λ = 3.611 A⁰ = 3.611 × 10⁻¹⁰ m
h = 6.626 × 10 ⁻³⁴
V = 3 × 10⁸ m/s
---------------------------------
--------------------------------------------------
∴ M = ( 6.626 × 10 ⁻³⁴ ) / [ ( 3.611 × 10⁻¹⁰ ) × ( 3 × 10⁸)]
= 6. 116 × 10⁻³³ kg //
