the reflected intensity of light normally incident on an interface betweentwo transparent media. (a) For light normally incident on an interface between vacuum and a transparent medium of index n, show that the intensity S2 of the transmitted light is given by S2/S1 = 4n/(n + 1)2. (b) Light travels perpendicularly through a diamond slab, surrounded by air, withparallel surfaces of entry and exit. Apply the transmission fraction in part (a) to find the approximate overall transmission through the slab of diamond, as a percentage. Ignore light reflected back and forth within the slab.

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.
