Transcribed Image Text:9. Light that comes from a source with two different wavelengths shines through two slits that are
separated by 2.33 x 104 m. On the viewing screen the first two bright fringes are measured at angles 15.2
and 19.7°.
a. What is the difference (in nm) between the two wavelengths whose fringes are seen in the pattern?
b. At what angle would the NEXT bright fringe be seen on the viewing screen?
- 3) Including the fringe at the center of the screen, how many bright fringes for the larger of the two
wavelengths could possibly been seen on the screen?
