Homework Statement



A construction company designs a new office tower with an outer surface mostly made of glass(n glass = 1.52). The company wishes that the glass appear a reddish-orange without having to use coloured glass. Instead, a thin film (n film = 1.65) is used that maximizes the reflection of that colour of light (wavelength 615 nm). What thickness would this film need to be?


Homework Equations



n coating = wavelength glass/wavelenght coating

The Attempt at a Solution



wavelength coating = (615 * 10^-9)/(1.65)
= 3.73 * 10^-7 m

t = 3.73 * 10^-7 m/4
= 9.32 * 10^-8 m

****I really don't think this is right, could someone help me out with a step-by-step solution. Thank you so much! :)
