  • When a Ï€ rad phase change occurs upon reflection from both the front and back surfaces of a thin film, constructive interference occurs if half a wavelength fits in twice the film thickness.

  • When a Ï€ rad phase change occurs upon reflection from both the front and back surfaces of a thin film, constructive interference occurs if a full wavelength fits in twice the film thickness.

  • When a Ï€ rad phase change occurs upon reflection from the front but not the back surface of a thin film, constructive interference occurs if half a wavelength fits in twice the film thickness.
