Fantastic news! We've Found the answer you've been seeking!

A lens made of glass n=1.52 is coated with a thin film of MgF2 n=1.38 of thickness t.Visible light is incident normally on the coated lense.For what minimum value of t will the reflected light of wavelength 5.4×10^2 nm be missing?Are there other values of t that will minimise the reflected light at this wavelength.explain.
