Question

A sodium lamp (= 589.3 nm) illuminates a wedge that has been set up as shown in the picture below. glass Flat surface Flat surface glass d The distance between 15.7 fringes is given by 31.5 mm. What angle does the wedge make? 0 = 1.40E-4 X radians Check Incorrect Marks for this submission: 0.00/1.00. This submission attracted a penalty of 0.33. The apparatus is now immersed in water with a refractive index of n = 1.33. What is the distance between successive fringes now? mm Check
