Question
Chapter 8, Problem 2RQ
To determine
The photosphere’s color as viewed from the ground on a clear, cloudless day at the Sun is overhead; the sun is above the ocean’s horizon; the sun is half below the ocean’s horizon.
Is the photosphere changing the colors during this sunset.

Students have asked these similar questions
If the color of the sun's photosphere's maximum intensity light is green, is this the color we normally observe for the photosphere? Why or why not?
(I would assume it is not, but I do not know why...)
How many watts of radiation does a 1-meter square region of the Sun's photosphere emit at a temperature of 500 K ?
How much would the wattage increase if the temperature was doubled?
62. Pressure of the Photosphere. The gas pressure of the photosphere
changes substantially from its upper levels to its lower levels.
Near the top of the photosphere, the temperature is about 4500 K
and there are about 1.6 x 1016 gas particles per cubic centimeter.
In the middle, the temperature is about 5800 K and there are
about 1.0 x 10" gas particles per cubic centimeter. At the bottom
of the photosphere, the temperature is about 7000 K and there
are about 1.5 × 10" gas particles per cubic centimeter. Use the
ideal gas law (Mathematical Insight 14.2) to compare the
pressures
of each of these layers; explain the reason for the trend
that you find. How do these gas pressures compare with Earth's
atmospheric pressure at sea level?

- Make a sketch of the Sun’s atmosphere showing the locations of the photosphere, chromosphere, and corona. What is the approximate temperature of each of these regions?arrow_forwardFrom the information in Figure 15.21, estimate the speed with which the particles in the CME in parts (c) and (d) are moving away from the Sun. Figure 15.21 Flare and Coronal Mass Ejection. This sequence of four images shows the evolution over time of a giant eruption on the Sun. (a) The event began at the location of a sunspot group, and (b) a flare is seen in far-ultraviolet light. (c) Fourteen hours later, a CME is seen blasting out into space. (d) Three hours later, this CME has expanded to form a giant cloud of particles escaping from the Sun and is beginning the journey out into the solar system. The white circle in (c) and (d) shows the diameter of the solar photosphere. The larger dark area shows where light from the Sun has been blocked out by a specially designed instrument to make it possible to see the faint emission from the corona.
