you have a lens system that is to be used primarily for
675 nm red light.
Magnesium fluorite index of refraction = n =
1.38
Second thinnest coating of magnesium fluorite that would be
non-reflective for this wavelength = t = 366.8 nM
Assuming the index of refraction of the lens is bigger than
1.38.
Draw a diagram of the mediums showing where, if any, a
phase change occurs. State whether you are looking for constructive

A thin filme of acetone (n=1.26) coats a plate of glass (n=1.5).
White light is incident normal on to the film. In the reflections,
fully destructive interference happens at 598 nm and fully
constructive interference happens at 747.5 nm.

Interference patterns do not have an infinite number of lines,
since there is a limit to how big can be.If you pass red light with
λ1= 670 nm wavelength through two slits separated by an unknown
distance, the highest order of constructive interference possible
is m1= 15. Show that the maximum value of m2 is 26, the highest
order of constructive interference possible when bluelight with λ2=
410 nm wavelength is used on same slits separated by same unknown
distance.
