wavelength = h/mv. m in kg. v in m/s
Substitute the numbers and solve. Post your work if you get stuck. This is just a case of plugging in the numbers and turning the crank.
Calculate the de Broglie wavelength of the following.
(a) An electron moving at a speed of 1.08×103 m s-1.
(b) A proton moving at a speed of 1.08×103 m s-1.
(c) A baseball with a mass of 147 grams moving at a speed of 33.1 m s-1.
(a) Wavelength electron =
m
(b) Wavelength proton =
m
(c) Wavelength baseball =
m
