What is full name of UV rays originating from sun?

Answer 1

UV rays of the sun refer to the *Ultraviolet* rays of  the sun

Answer 2

UV beams of the sun allude to the *Ultraviolet* beams of the sun.

The climate obstructs around 77% of the Sun's UV, essentially in the shorter UV wavelengths, when the Sun is most astounding in the sky (apex).

Of the bright radiation that achieves the Earth's surface, over 95% is the more drawn out wavelengths of UVA, with the little leftover portion UVB. There is basically no UVC.
