A Young's interference experiment is conducted with blue-green argon laser light (l = 515 nm). The separation between the slits is 0.50 mm, and the interference pattern appears on a screen 4.95 m away. What is the spacing between the bright fringes? (1 nm = 10-9 m)
a. 3.4 mm
c. 1.7 mm
b. 5.1 mm
d. 6.8 mm
Question 2
If the m = 2 fringe in Young's double-slit experiment occurs at an angle of 45.0, what is the relationship between the wavelength l and the distance between slits, d?
a. d = 2.00l
c. d = 1.41l
b. d = 2.83l
d. d = 4.00l
