What is the de Broglie wavelength (m)of a 2.0-kg object moving at a speed of 50 m/s?

Question

Quizplus · Accepted Answer

The de Broglie wavelength $\lambda$ can be calculated using the formula $\lambda = \frac{h}{mv}$, where $h$ is Planck's constant ($6.626 \times 10^{-34} \, \text{m}^2\text{kg/s}$), $m$ is the mass of the object, and $v$ is the velocity of the object. Substituting the given values ($m = 2.0 \, \text{kg}$, $v = 50 \, \text{m/s}$), we get $\lambda = \frac{6.626 \times 10^{-34}}{2.0 \times 50} = 6.6 \times 10^{-36} \, \text{m}$.
