Calculate the wavelength of a baseball (m = 155 g) moving at 32.5 m s^-1. 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 de Broglie wavelength of an object is given by λ = h/p, where h is Planck's constant and p is the momentum of the object. We can find the momentum of the baseball using p = mv, where m is the mass of the baseball and v is its velocity.

p = (0.155 kg)(32.5 m/s) = 5.04 kg m/s

Now we can calculate the wavelength:

λ = h/p = (6.626 × 10^-34 J s)/(5.04 kg m/s)

λ = 1.32 × 10^-34 m

Therefore, the correct answer is choice B.
