Diffraction Grating -Grooves are cut out at regular spacings d A grating of unknown number of lines per centimeter is used in an experiement. A green light of a wavelength of 520.0 nm passes the grating. The distance between the grating and the screen is L = 2.4 m. On the pattern formed on the screen, the distance between the 3rd order maximum and the central maximum is 2.345 m. (a) What is the angle of the 3rd order maximum relative to the incident light. Keep 2 decimal places. Enter a number Submit (2 attempts remaining) (b) What is the separation d between two adjacent lines in the grating? Report the d in terms of 10° decimal places. m (micrometer, µm). Keep 4 Enter a number µm 0 Submit (2 attempts remaining) (c) How many lines per centimeter does the new grating have? Round to an integer. Enter a number Submit (2 attempts remaining)
