To confirm the wavelength of a new laser, a scientist prepares a diffraction grating with a distance of 5.00x10^-6 m between slots and places it in front of the laser which is 1.50 m in front of a screen. The scientist measures the distance from the central maxima to the second bright fringe, which is 0.330 m. What is the wavelength of the laser?
