A monochromatic laser of wavelength 610.00nm to pointed perpendicular to a diffraction grating. On a screen 120 cm away, the fourth order maximum is observed to be at a distance of 46 cm from the central maximum. Given this observation, what angle does the fourth order maximum make with respect to the direction of the incident laser beam? how many lines pwer millimeter mst the grating have to produce this patter? Note: the small angle approximation will not work her!
Angle fourth order max makes:________degrees
Diffraction gating lines per millimeter:___________lines/mm
What is the distance between the two traps?
