What is the wavelength of the matter wave associated with a 0.50-kg ball moving at 25 m/s? (h = 6.626 × 10^-34 J ∙ s) A)3.5 × 10^-35 m B)5.3 × 10^-35 m C)3.5 × 10^-33 m D)5.3 × 10^-3³ m

Question

Quizplus · Accepted Answer

The de Broglie wavelength (λ) of an object is given by λ = h/mv, where h is Planck's constant, m is the mass of the object, and v is its velocity.
Plugging in the given values, λ = 6.626×10^-34 J∙s / (0.50 kg)(25 m/s) = 5.3 × 10^-35 m. Therefore, the best choice is B.
