If the atmosphere were twice as thick as it currently is (extending farther into
space), what effect would this have on the color the sun would appear to be?
It would look whiter
It would look redder
It would have no effect
O It would look bluer
The intensity of light from a central source varies inversely as the square of the distance. If you lived on a planet only half as far from the Sun as our Earth, how would Sun’s light intensity compare with that on Earth? How about a planet 10 times farther away than Earth?

- The 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_forwardContinuing the thinking in Exercise 29.27 and Exercise 29.28, calculate the energy in a cubic meter of space, multiply the energy per photon calculated in Exercise 29.26 by the number of photons per cubic meter given above.arrow_forwardIf one star has a temperature of 6000 K and another star has a temperature of 7000 K, h much more energy per second will the hotter star radiate from each square meter of its surface?arrow_forward
