Question 8 (a) Monochromatic light illuminates two slits seperated by 1.2 mm, creating pattem on a screen 3.6 mm from the slits. The distance between the third and sixth dark fringes on the screen is 5.3 mm. (a) What is the wavelenght of the lightr? (b) The witdh of each slit in part (a) is a = 0.15 mm, what is the width of the central difraction maximum on the screen and how many bright fringes (i.e, interference maxima) are contained within it?
