1. The problem statement:
A wavelength (λ)550 nm light ray traveling thru a viscous medium n1= 1.46 strikes a a crystal n3=1.5 protected by a film n2=1.25.
2. Relevant equation:
How can I determine the min thickness of the antireflective coating used to minimize the reflection of the incident light?
I think I can determine it by using
2t+0.5λ1+0.5λ3= (m+0.5)λ2 where m=1 and then solving for t.
Any guidance would be greatly appreciated.
