Laser light of wavelength 632.8 nm passes through a diffraction grating with a line density of 5,300 lines/cm. The interference pattern is observed on a wall 0.9 meters in front of the diffraction grating. Second max. Central max. Calculate the distance (in meters) between the 2nd bright spot the central maximum. Warning: the small angle approximation leads to significant errors for angles bigger than 10 degrees.
