- If the emitted infrared radiation from Pluto, has a wavelength of maximum intensity at 75,000 nm, what is the temperature of Pluto assuming it follows Wien’s law?arrow_forwardThe edge of the Sun doesn’t have to be absolutely sharp in order to look that way to us. It just has to go from being transparent to being completely opaque in a distance that is smaller than your eye can resolve. Remember from Astronomical Instruments that the ability to resolve detail depends on the size of the telescope’s aperture. The pupil of your eye is very small relative to the size of a telescope and therefore is very limited in the amount of detail you can see. In fact, your eye cannot see details that are smaller than 1/30 of the diameter of the Sun (about 1 arcminute). Nearly all the light from the Sun emerges from a layer that is only about 400 km thick. What fraction is this of the diameter of the Sun? How does this compare with the ability of the human eye to resolve detail? Suppose we could see light emerging directly from a layer that was 300,000 km thick. Would the Sun appear to have a sharp edge?arrow_forwardWhy are ionized gases typically only found in very high-temperature environments?arrow_forward

This has led to many thirsty travelers in deserts seeing a lake of “water”; or drivers on a highway seeing a “water or oil” spill ahead, where there is none. Discuss what would happen if the air grows gradually warmer as the height is increased? This often happens over bodies of water or ice/snow-covered ground. This effect is called “Looming” or a “superior mirage.” (Hint: Cooler air will have a refractive index that is higher than warmer air. Use a diagram/drawing to help with the visualization of layers of different temperature air and to explain this effect.)arrow_forward
