(a) what is separation between slits (b) what is the unknown wavelength (c) what is maximum m order for unknown wavelength

[25 pts] 380 nm light passes through a pair of slits and creates an interference pattern on a screen 1.4 m behind the slits. The figure below shows the light intensity on the screen. [Answer in 3 significant figures] Intensity Central maximum 2.45 cm a. [13 pts] What is the separation between the slits? Name: b. [6 pts] The 9th bright fringe of an unknown wavelength overlaps the 13th bright fringe of the 380 nm light. What is the unknown wavelength? c. [6 pts] What is the maximum m order for this unknown wavelength
