The gure shows a red line and a green line of the same order in the pattern produced by a diffraction grating. D]: If we increased the number of rulings in the gratingsay, by removing tape that had covered the outer half of the rulings would the half-widths of the lines increase, decrease, or remain the same? 0 Increase O Decrease O Remain the same Would the separation of the lines increase, decrease, or remain the same? O Remain the same O Decrease O Increase Would the separation of the lines increase, decrease, or remain the same? O Remain the same 0 Decrease O Increase Would the lines shift to the right, shift to the left, or remain in place? 0 Remain in place O Shift left 0 Shift right View POIICIes Current Attempt in Progress A beam of light consisting of wavelengths from 465 nm to 635 nm is directed perpendicularly onto a diffraction grating with 145 lines/mm. (a) What is the lowest order that is overlapped by another order? (b) What is the highest order for which the complete wavelength range of the beam is present? In that highest order, at what angle does the light at wavelength (c) 465 nm and (d) 635 nm appear? (e) What is the greatest angle at which the light at wavelength 465 nm appears? (a) Number n Units v (b) Number n Units v (c) Number l Units v (d) Number n Units v (e) Number n Units v eTextbook and Media Current Attempt in Progress A grating has 380 rulings/mm and is 6.5 mm wide.
