You are observing light interference from the top of a soap bubble that is resting on a countertop. The index of refraction of the soap bubble is n = 1.29. At this moment, the reflection in the soap bubble has a wavelength of 1 = 5,92e-07 meters. Your eye White Light One Color d Soap Bubble What is the THINNEST film that can produce this color? d = meters. As time goes on, the soapy water accumulates near the bottom of the bubble making the top VERY VERY thin (d ). What happens at this point? O Longer wavelength (more VIOLET) reflection Shorter wavelength (more RED) reflection Shorter wavelength (more VIOLET) reflection WHITE reflection NO reflection Longer wavelength (more RED) reflection
