When light strikes an oil film at an angle, some of the light is reflected from the top surface of the oil, and some is reflected from the bottom surface where it is in contact with the water. Because the light reflecting from the bottom travels a slightly longer path, some light wavelengths are reinforced by this delay, while others tend to be canceled, producing the color… reloading 410 shotshellsWebDec 1, 2015 · The dichroic ratio R was calculated at maximum absorption wavelength. 3.
