Problem: How to calculate the wavelength of a baseball (m = 155 g) moving at 32.5 m/s?

FREE Expert Solution

de Broglie wavelength (λ):


λ=hmv


where:

h = Planck's constant (6.626 × 10–34 kg • m2/s)

m = mass (in kg)

v = velocity (in m/s)


We’re given:

mass = 155 g           velocity = 32.5 m/s


m=155 g×1 kg103 g

m = 0.155 kg
