An optician 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 0.190 mm. An interference pattern appears on a screen that lies 5.25 m from the slit pair. The instructor's measurements show that two adjacent bright interference fringes lie 1.60 cm apart on the screen.
Required:
What is the laser's wavelength (in nm)?
