Question
Chapter 7, Problem 1RQ
To determine
Why we cannot see below photosphere in sun.
Expert Solution & Answer
Explanation of Solution
Part of the sun that can observe directly are photosphere, chromosphere, and corona. As we move deeper, the gas gets denser. Gas below the photosphere is enough to produce a continuous spectrum, but atom present in photosphere won’t allow the light to pass through. Almost no light seems to emerge below the photosphere. That’s why we can’t see deeper into the sun that the photosphere.

- What is the average density of the Sun? How does it compare to the average density of Earth?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.
