Calculate the wavelength of a baseball (m = 155 g)moving at 32.5 m/s. A) 7.60 × 10^-36 m B) 1.32 × 10^-34 m C) 2.15 × 10^-32m D) 2.68 × 10^-34 m E) 3.57 × 10^-32 m

Question

Quizplus · Accepted Answer

The wavelength of an object is given by the formula λ = h/mv where h is the Planck's constant, m is the mass of the object and v is its velocity. Plugging in the given values, we get:

λ = (6.626 × 10^-34 J s) / (0.155 kg × 32.5 m/s) 
λ = 1.32 × 10^-34 m

Therefore, the wavelength of the baseball is 1.32 × 10^-34 m, which is closest to option B.
