Young’s Double Slit and Single Slit Experiments practice problem 

Below is an image of the fringe pattern produced by two identical slits and light of wavelength 𝜆 = 600 𝑛𝑚. The pattern is produced on a screen 1.0 𝑚 from the slits. Using the provided scale, determine the separation between the slits and the width of one individual slit. Explain your reasoning.
