Please answer provide an accurate answer by your work, Really thanks for that.
What would be the refractive index of the perfect quarter wave anti-reflection coating for flint glass with n = 1.72?
(Hints: the perfect QW coating would give a reflection amplitude of zero. The answer depends on the refractive index of the material being
coated, so take that into account.)
