A glass cover is placed over a water drop on a glass slide. When this is done, orange light (A = 605 nm in air) is reflected particularly strongly. What is the minimum possible thickness (nm) of water between the cover and slide? The index of refraction of the glass (cover and slide) is 1.54 and is 1.33 for water. The slide is too thick to be a thin film, just consider the water sandwiched between the cover and slide to be the film. 369 O 227 O 398 151 O 284 O 512 455 O 199 302 O 114
