Answer:
The wavelength of a proton is 1.36x10⁻¹⁵ m.
Explanation:
To find the wavelength (λ) of a proton we need to use the Broglie wave equation:
[tex] \lambda = \frac{h}{mv} [/tex]
Where:
h: is the Planck's constant = 6.62x10⁻³⁴ J.s
m: is the proton's mass = 1.673x10⁻²⁴ g = 1.673x10⁻²⁷ kg
v: is the proton's speed = 2.90x10⁸ m/s
[tex]\lambda = \frac{h}{mv} = \frac{6.62\cdot 10^{-34} J.s}{1.673\cdot 10^{-27} kg*2.90 \cdot 10^{8} m/s} = 1.36 \cdot 10^{-15} m[/tex]
Therefore, the wavelength of a proton is 1.36x10⁻¹⁵ m.
I hope it helps you!
