Solar cells are given antireflection coatings to maximize their efficiency. Consider a silicon solar cell (n=3.50$n=3.50$) coated with a layer of silicon dioxide (n=1.45$n=1.45$).

What is the minimum coating thickness (but not zero) that will minimize the reflection at the wavelength of 704 nm$\mathrm{n}\mathrm{m}$ where solar cells are most efficient?
