Question
Using $\Delta y = \dfrac{x\lambda}{d}$, calculate the distance between fringes for 633-nm light falling on double slits separated by 0.0800 mm, located 3.00 m from a screen as in Figure 27.56.
Question Image
<b>Figure 27.56</b> The distance between adjacent fringes is a function of the distance to the screen, wavelength, and slit separation, assuming the slit separation is large compared with the wavelength.
