To solve the problem step by step, we will use the principles of wave optics related to single-slit diffraction. ### Step 1: Identify the given values - Wavelength of light, \( \lambda = 600 \, \text{nm} = 600 \times 10^{-9} \, \text{m} \) - Width of the slit, \( d = 1 \, \text{mm} = 1 \times 10^{-3} \, \text{m} \) - Distance from the slit to the screen, \( D = 2 \, \text{m} \) ### Step 2: Understand the formula for the position of the dark fringes ...
