Explanation:

Effective Temperature of the Sun:
- The effective temperature of the sun is a measure of the temperature of the photosphere, which is the outer shell of the sun that emits light.
- This temperature is usually taken as 6000 K.

Reasoning:
- The effective temperature of the sun is determined by measuring the intensity of sunlight reaching the Earth and comparing it to the known intensity of sunlight emitted by a black body at a certain temperature.
- By using this method, scientists have determined that the effective temperature of the sun is around 6000 K.

Significance:
- The effective temperature of the sun is important for understanding the physical processes that occur in the sun, such as nuclear fusion reactions that produce its energy.
- It also helps in studying the behavior of other stars in the universe, as the sun is a common reference point for comparison.

Conclusion:
- In conclusion, the effective temperature of the sun, which is taken as 6000 K, is a crucial parameter for understanding the sun's properties and its role in the universe.
