What is the de Broglie wavelength of a ball of mass 200. g moving with a speed of 30. m/s?

Question

Quizplus · Accepted Answer

The de Broglie wavelength $\lambda$ is given by $\lambda = \frac{h}{mv}$, where $h$ is Planck's constant ($6.626 \times 10^{-34} \, \text{m}^2\text{kg/s}$), $m$ is the mass in kilograms, and $v$ is the velocity in meters per second. Converting the mass of the ball to kilograms (0.2 kg) and using the given velocity (30 m/s), the calculation is $\lambda = \frac{6.626 \times 10^{-34}}{0.2 \times 30}$, which results in approximately $1.1 \times 10^{-34}$ meters.
