Select all the true statements about this situation. (select all that apply.) for completely destructive interference to occur at the orange point, the path-length difference for the orange point must be an integer number of wavelengths plus half a wavelength. the path-length difference is the distance the point is from the left source minus the distance the point is from the right source in this particular case, the orange point is 1.5 wavelengths farther from the left source than it is from the right source when we say that completely destructive interference occurs at the orange point, the net displacement must be zero at all times at that point. for completely destructive interference to occur at the orange point, the distance from each source to the orange point must be an integer number of wavelengths plus half a wavelength. (b) in this case, what is the distance between the two sources, in terms of wavelengths? x wavelengths (c) let's say that the wavelength in this case is 20.0 cm, and the distance from the source on the right to the orange point is 70.0 cm. what is the distance from the source on the left to the orange point? cm
