Calculate the de Broglie wavelength of a ball of mass moving with a speed of . () — Atomic Structure Chemistry Question

💡 Solution & Explanation

Using the de Broglie equation $\lambda = \frac{h}{mv}$, we substitute the given values: $\lambda = \frac{6.6 \times 10^{-34}}{0.1 \times 30} = \frac{6.6 \times 10^{-34}}{3} = 2.2 \times 10^{-34} \text{ m}$.
