Young's Double Slit Experiment: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Young's Double Slit Experiment. Understanding the underlying formula is key to arriving at the correct answer below:

The distance of the nth maximum from the central maximum is $x = \frac{n\lambda D}{d}$. Thus, $x \propto \lambda$. Since $\lambda_{blue} < \lambda_{green}$, it follows that $x(blue) < x(green)$.
