WebOct 1, 2014 · For example, light traveling through 10 cm of water has an optical path length of 10 x 1.333 or 13.3 cm. The geometric length is simply the physical distance the light travels. The optical path length is important because it allows us to find out what the phase of the light will be at any point, whereas the geometrical length doesn't. c1 = n * c2. WebSolution Suppose light travels a distance 'd' in time interval 'T' then the distance traveled by light in a vacuum in the same time interval is known as optical path length. In other words, …

WebAs the optical path difference, OPD, is increased, different wavelengths produce peak readings at different positions, and for a broadband signal, they never again reach their peaks at the same time.
