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

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.
