3) You are working with a lab instrument that has a diffractiongrating of 600lines/mm. 450nm wavelength light passes through thegrating 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 spotson the screen? c. If you instead send red (650nm) light through thescreen, would this increase or decrease the spacing on the screen?Find the distance between two bright spots with red light.
