1. Two slits with a separation of 8.5 x 10^(-5) m create an interference pattern on a screen 2.3 m away.
A) If the tenth fringe above the central bright fringe is a linear distance 12 cm above the central fringe, what is the wavelength of the light used in the experiment?
B) What is the linear distance from the central bright fringe to the tenth dark fringe above it?
