Suppose NASA sent a robotic craft to explore the deep oceans of Jupiter’s moon, Europa (assume the ocean water has an index of refraction 1.34) . In an attempt to be discrete, NASA applies a coating to the submarine-like craft, to make it indetectable to any creatures in the ocean who can see light with a wavelength of 1200nm. The coating material has anindex of refraction of 1.25.a) Draw a clear physics diagram of the problem.b) Technology only allows for coatings to be 1 micrometer or thicker. What is the thinnest coating that can be applied to the craft to make it invisible at 1200nm.

Unpolarized light passes through successive polarizers sheets, each of whose axis makes a 20° angle with the previous one. How many polarizers in total are required for the output intensity to be lower than 25% of the input intensity?
Application: Assume a small spacecraft is in open space. One panel is a dedicated radiator (dimensions in image) and is painted with S13 GLO white paint (emissivity = .89). If the radiator is at 30C and has a full view factor to space, how much heat can it reject from the system? (How much is this radiator radiating to space?). Use 3K for space temperature. Round answer up to one decimal place. No need to include units. (Remember that -/+ signs are used in respect to direction of energy transfer) h 37°F Cloudy HD GAN .1 m Radiator .3 m Q Search
