A) For use in a liquid crystal display, you want an electrode that is transparent to all visible light. You decide to use a doped semiconducting oxide with a mobility of 10^(-2) m^2/V-s. What is the maximum conductivity you can expect from your oxide?
B) You look at the sun through goggles that have been coated with a thin layer of highly conductive metal such as silver. BRiefly explain why and in which way the color of light will be altered.
