In a two-slit interference experiment, a viewing screen is placed 5 meters directly behind two slits separated by 4 µm. coherent, monochromatic light of wavelength λ = 700 nm emerges (in phase) from the slits. (assume the slit width is very small compared to the wavelength λ.) 24. at what value of x on the screen does the largest-order intensity maximum occur (i. e., the one that is the farthest from the center line)? a. x = 1.2 mb. x = 4.4 mc. x = 5.0 md. x = 9.0 me. x = 15.7 mwhat happens to the separation between the existing intensity maxima on the screen as we increase the slit spacing? a. the separation decreases. b. the separation increases. c. there is no change.
