3) You are working with a lab instrument that has a diffraction grating of 600lines/mm. 450nm wavelength light passes through the grating and hits a screen 2m away from the grating.
a. What is the spacing between the lines of the grating? b. Given this spacing, what is the distance between two bright spots on the screen? c. If you instead send red (650nm) light through the screen, would this increase or decrease the spacing on the screen? Find the distance between two bright spots with red light.
