Question

How is a water heater made with the help of a concave mirror?

Answer 1

Concave mirror traps more heat and creates greenhouse effect

Answer 2

In fact, Ozone has been called “Enhanced Oxygen” for the simple reason that Oxygen (O2) can be converted to Ozone (O3). Ozone is produced naturally in the upper atmosphere (the Ozone layer) through ultraviolet radiation. As well, lightning will produce Ozone through electrical excitation of Oxygen molecules.
