A Young's interference experiment is performed with blue-green argon laser light. The separation between the slits is 0.404 mm, and the interference pattern on a screen 3.12 m away shows the ?rst maximum 3.19 mm from the center of the pattern.
What is the wavelength of argon laser light? Answer in units of nm.
