The three rays coming from the Sun are not commonly referred to by specific names. However, if you are referring to the three main components of solar radiation, they are:
Ultraviolet (UV) rays: These rays have shorter wavelengths than visible light and are not visible to the human eye. UV rays are categorized into three types: UVA, UVB, and UVC, based on their wavelengths. UVC rays are typically absorbed by the Earth's atmosphere and do not reach the surface.
Visible light: This is the portion of the electromagnetic spectrum that is visible to the human eye. It consists of different colors ranging from violet to red, with each color corresponding to a different wavelength.
Infrared (IR) rays: These rays have longer wavelengths than visible light and are also not visible to the human eye. Infrared radiation can be further divided into near-infrared, mid-infrared, and far-infrared, based on their wavelengths.
It's important to note that while the Sun emits various types of radiation, these three categories are commonly referred to when discussing the components of solar radiation.
