Question

Quizplus · Accepted Answer

The de Broglie wavelength $\lambda$ is given by $\lambda = \frac{h}{mv}$, where $h$ is Planck's constant (6.626 × 10^-34 J·s), $m$ is the mass of the object (1.30 kg), and $v$ is the velocity of the object (28.10 m/s). Plugging in the values, $\lambda = \frac{6.626 \times 10^{-34}}{1.30 \times 28.10} \approx 1.81 \times 10^{-35} \, \text{m}$.
