Waves from two slits are in phase at the slits and travel to a distant screen to produce the second minimum of the interference pattern. The difference in the distance traveled by the wave is: Group of answer choices three wavelengths three halves of a wavelength half a wavelength a wavelength two wavelengths
path difference between waves at minimum is (2n+1)*wavelength /2 therefore at second minimum it is for n=1=1.5 times a wavelength. or three halves a wavelength
