Question
**Physics Experiment: Double Slit Interference** **Experiment Description:** Light from a helium-neon laser with a wavelength of \( \lambda = 633 \, \text{nm} \) is used to illuminate two narrow slits. The resulting interference pattern is projected onto a screen located \( 3.4 \, \text{m} \) behind the slits. In this pattern, twelve bright fringes are visible, spanning a total distance of \( 53 \, \text{mm} \). **Problem Statement:** **Part A** What is the spacing (in mm) between the slits? *Express your answer using two significant figures.* **Attempt:** - The user entered: \( d = 0.49 \, \text{mm} \) - Response: Incorrect; Try Again; One attempt remaining.
