The temperature of photosphere of Sun is

Options

A. `10^(7)` K
B. `10^(5)` K
C. `10^(4)` K
D. `10^(3)` K

Answer

To find the temperature of the photosphere of the Sun, we can follow these steps:

### Step 1: Understand the Structure of the Sun
The Sun is composed of several layers, each with different characteristics. The main layers include:
- Core
- Radiation Zone
- Convection Zone
- Photosphere
- Chromosphere
- Corona

### Step 2: Identify the Photosphere
The photosphere is the layer of the Sun that is visible to us. It is the outermost layer of the Sun's atmosphere and is where sunlight is emitted.

### Step 3: Research the Temperature of the Photosphere
The temperature of the photosphere is a well-documented scientific fact. It is known to be approximately 5,500 degrees Celsius (or about 5,800 Kelvin).

### Step 4: State the Temperature
Thus, the temperature of the photosphere of the Sun is approximately 5,800 K.

### Final Answer
The temperature of the photosphere of the Sun is approximately 5,800 K.
