What is ph level, what are its characteristics, and how does it contribute to pollution?

pH Scale:

The pH scale refers to the negative logarithm of molar concentration of hydrogen ions: pH = -log [H+].

Characteristics:

The pH scale ranges from 0 to 14. A solution of a compound of pH 7 or pOH 7 is a neutral solution. Solutions of pH less than 7  are acidic and more than 7 are basic.

Low pH of water is acidic in nature as it enters into the ground and collects in streams, it can have bad impacts on the ecosystem.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
