which is an accurate statement about the different types of radiation emitted by the sun

radiation with the longest wave lengths is most likely to cause a wide variation in total star irradiance
radiation with the longest wave lengths is emitted steadily and constantly by the sun
radiation with the shortest wave lengths is most likely to cause a wide variation in total star irradiance
radiation with the shortest wave lengths is emitted steadily and constantly by the sun

The most accurate statement about the different types of radiation emitted by the sun is: "Radiation with the longest wavelengths is most likely to cause a wide variation in total star irradiance."
