Question 1 A laser with a wavelength of 491 nm illuminates two narrow slits. The interference pattern from the double slits is viewed on a screen that is 2.80 m away. Over a distance of 48.0 mm there are 14.0 bright fringes. What is the spacing between the two slits? |:] Question 2 It's nighttime, and you've dropped your goggles into a 3.65 m deep swimming pool. If you hold a laser pointer 0.500 m above the edge of the pool, you can illuminate the goggles if the laser beam enters the water 1.91 m from the edge. How far are the goggles from the edge of the pool
