Answer to Question #116150 in General Chemistry for SOPHIA

General Chemistry

Question #116150

Calculate the de Broglie wavelength for a proton with a velocity 4.13% of the speed of light.

m

Expert's answer

h = 6.626 × 10^-34

v = 4.13/100 * 299 792 458 = 12381428.5 m/s

m (proton) = 1.67 × 10^-27kg

λ = 6.626 × 10^-34 / (1.67 × 10^-27 * 12381428.5) = 3.2 x 10^-14 m
