To solve the problem step by step, we will use the information provided in the question and apply the relevant formulas. ### Step 1: Understand the Shift in Fringes The problem states that the central fringe shifts by 5 fringe widths due to the introduction of a mica sheet. The shift in the position of the fringe can be expressed as: \[ \Delta x = n \cdot \lambda \] where \( n \) is the number of fringe widths shifted (in this case, \( n = 5 \)) and \( \lambda \) is the wavelength of light. ...
