Visible light of variable wavelength is incident normally on a thin sheet of plastic in air. The reflected light has a minima only for \(\lambda=512 \mathrm{~nm}\) and \(\lambda=640 \mathrm{~nm}\) in the visible spectrum. What is the minimum thickness (in \(\mu \mathrm{m}\) ) of the film \((\mu=1.28)\) ? 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
