MY NOTES ASK YOUR TEACHER A technician wishes to determine the wavelength of the light in a laser beam. To do so, she directs the beam toward a partition with two tiny slits separated by 0.180 mm. An interference pattern appears on a screen that lies 5.15 m from the slit pair. The technician's measurements show that two adjacent bright interference fringes lie 1.59 cm apart on the screen. What is the laser's wavelength (in nm) ? nm Submit
