need answer in 10 min
A Silicon (Si) substrate is coated on one side with a thin film of ZnO to reduce reflection from the Si surface. The index of refraction of ZnO is 1.850 and the Si is 3.881. What is the least coating thickness that eliminates (via interference) the reflections at the middle of the visible spectrum (-600 nm)? (Angle of incidence is normal.) Draw the suitable diagram.
