The irradiance of the sun is dependent on the following factors:
1. The wavelength of the radiant energy it emits: Different wavelengths of light have different amounts of energy, and the sun emits a wide range of wavelengths. The total amount of energy emitted by the sun at different wavelengths affects the overall irradiance.
2. The density of particles in the solar wind: The sun continuously emits a stream of charged particles called the solar wind. The density of these particles can affect the irradiance of the sun, as interactions between the solar wind particles and the Earth's magnetic field can produce auroras and other effects.
3. The number of sunspots: Sunspots are dark spots that appear on the surface of the sun due to changes in its magnetic field. The number of sunspots can vary over time, and this variation is known as the solar cycle. Changes in the number of sunspots can affect the sun's overall irradiance.
4. The energetic solar wind particles: In addition to the density of particles in the solar wind, the energy and speed of these particles can also affect the sun's irradiance. High-energy particles can cause disturbances in the Earth's magnetic field and contribute to space weather events.
Overall, the irradiance of the sun is influenced by a combination of these factors, among others.
