[題目] 有人可以幫我解就這一題嗎
In an experiment to observe fringes of equal inclination, the source emits
wavelengths of 500 nm and 600 nm. It is observed that a bright fringe is
obtained for both wavelengths when the light passes through the film at
cos^-1(0.7) to the normal, and that the next such coincidence occurs at
an angle cos^-1(0.8)
Deduce the optical thickness of the film and the orders of the fringes for
which the two coincidences occur.
今天老師出給我們的,完全不知道這題在幹嘛
有人可以跟我討論一下嗎 感恩><"
