Two waves of light in air have the same wavelength and are initially in the same phase. They then travel through plastic layers with thicknesses of L1=3.5 mm and L2=5.0 mm and indices of refraction n1=1.7 and n2=1.25 as shown in the figure. The rays later arrive at a common point. The longest wavelength of light for which constructive interference occurs at the point is |
