Question: A red laser from the physics lab is marked as producing 632.8-nm light. When light from this laser falls on two closely spaced slits, an interference pattern formed on a wall several meters away has bright red fringes spaced5.00mm apart near the center of the pattern. When the laser is replaced by a small laser pointer, the fringes are 5.13mm apart.
Part A: What is the wavelength of light produced by the pointer?
