- A Technician Wishes To Determine The Wavelength Of The Light In A Laser Beam To Do So He Directs The Beam Toward A Par 1 (10.79 KiB) Viewed 27 times
A technician wishes to determine the wavelength of the light in a laser beam. To do so, he directs the beam toward a partition with two tiny slits separated by 0.195 mm. An interference pattern appears on a screen that lies 4.90 m from the slit pair. The technician's measurements show that two adjacent bright interference fringes lie 1.56 cm apart on the screen. What is the laser's wavelength (in nm)? nm
