PDE Q3
0. Photosphere is described as the:
- Option : B
- Explanation :
The correct answer is:
B — Visible surface of the sun from which radiation emanates.
-
The photosphere is the layer of the Sun that we actually see with our eyes. It is often called the Sun’s “surface” even though the Sun is a gaseous body and does not have a solid surface.
-
It is the source of most of the sunlight (visible radiation) that reaches Earth.
-
The temperature of the photosphere is approximately 5,500 °C (about 5,800 K).
-
It is located above the Sun’s convective zone and below the chromosphere.
Other options are incorrect because:
-
Option A: The lower layer of the Earth’s atmosphere is called the troposphere, not the photosphere.
-
Option C: Wavelength of the solar spectrum is a property of light, not the photosphere itself.
-
Option D: Not applicable.
