what is light and what is pH level ? What is the uses of pH level ?
Answers
Light is a form of electromagnetic radiation with a wavelength which can be detected by the human eye. It is a small part of the electromagnetic spectrum and radiation given off by stars like the sun. Animals can also see light. The study of light, known as optics, is an important research area in modern physics.
In chemistry, pH is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution.
The pH can control the availability of nutrients, biological functions, microbial activity, and the behavior of chemicals. Because of this, monitoring or controlling the pH of soil, water, and food or beverage products is important for a wide variety of applications.

→ Light is a form of electromagnetic radiation with a wavelength which can be detected by the human eye.
→ pH LEVEL : pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
→ pH Measurement is used in a wide variety of applications:
• agriculture.
•wastewater treatment .
•industrial processes.
•environmental monitoring.
•research and development.
