- T or F? Huygens’s principle provides a foundation for wave optics and can explain observations such as light diffraction, but it fails to provide an explanation for the rules of geometric optics.Two sources of electromagnetic waves (light waves) are emitting coherent waves at a frequency of 546 THz. These two sources are located a distance d apart and aimed at point A, as shown below. If the top source is located a distance 3.8 meters away from point A, find the minimum distance d that will give destructive interreference. Enter your answer in millimeters. 4₁1 Laser Laser d AA sheet of glass (n=1.50) is coated with a 500 nm-thick layer of oil (n=1.42). A.
