Problem 3: Interference effects are produced at point \( P \) on a screen as a result of direct rays from a \( 500-\mathrm{nm} \) source and reflected rays from the mirror as shown in the figure. Assume the source is \( 10.0 \mathrm{~m} \) to the left of the screen and \( 1.00 \mathrm{~mm} \) above the mirror. (a) Find the distance \( y_{\text {bright-1 }} \) to the first bright fringe above the mirror. (b) Find the distance \( y_{\text {dark }-1} \) to the first dark fringe above the mirror.
