Two in-phase sources of waves are separated by a distance of 4.00m. these sources produce identical waves that have a wave length of 5.00m. on the line between them, there are two places at which the same type of interference occurs. 3) which type of interference occurs twice? constructive destructive 4) at what location from one of the sources does this interference occur? 0.5m and 3.5m 0.75m and 3.25m 1.5m and 2.5m 5) at what location from one of the sources does the other type of interference occur? 0.5m 1.0m 1.5m 2.0m a slit of width 4.30x10-5m is located 1.32m from a flat screen. light of wavelength 635nm is shining on the slit. 6) what is the width of the central bright fringe? .025m .039m .053m .067m
