After a laser beam passes through two thin parallel slits, the first completely dark fringes occur at ±15.0∘±15.0∘ with the original direction of the beam, as viewed on a screen far from the slits. What is the ratio of the distance between the slits to the wavelength of the light illuminating the slits?

Step 1

The dark fringes occur at angles where the path difference between the light from the two slits is an odd multiple of half the wavelength. The condition for dark fringes is given by the formula: \[ d \sin(\theta) = (m + \frac{1}{2}) \lambda \] where \(d\) is the Show more…
