The wings of tiger beetles are colored by interference due to thin cuticle-like layers. In addition, these layers are arranged in patches that are 60 mm across and produce different colors.The color you see is a pointillistic mixture of thin-film interference colors that varies with perspective. Approximately what viewing distance from a wing puts you at the limit of resolving the different colored patches according to Rayleigh’s criterion? Use 550 nm as the wavelength of light and 3.00 mm as the diameter of your pupil.

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.
