the energetic solar wind particles

Answer 1

The irradiance of the sun is largely dependent on the wavelength of the radiant energy it emits. This is because irradiance, which is power per unit area received from the sun's radiation, varies with the spectrum of the emitted light. Factors like the number of sunspots and solar activity can influence solar irradiance slightly but do not fundamentally define it as the wavelength does. Therefore, the correct response is the wavelength of the radiant energy it emits.
