Phys 201 Thin Film Interference 1 - Detailed Analysis & Overview
When an objects color depends on angle, it is due to In Unit 3 we said that only the first two reflections are strong enough to matter. Just in case, here we begin to add up the infinite ... Only the first two reflections are significant, so add them by superposition according to Unit 4% reflection from each glass surface adds up quickly. The phase term includes wavelength and angle, which explains the colors. To deal with the infinite reflections, write their coefficients in a systematic way to express it with a summation.
