Transboundary pollution is the pollution that originates in one country but is able to cause damage to another country's environment, by crossing borders through pathways like water or air. It is caused by a chemical reaction that begins when compounds like sulphur dioxide (SO₂) and nitrogen oxides (NO_x) are released into the air. Acid rain is an example of Transboundary pollution.

Acid rain is caused by a chemical reaction that begins when compounds like sulphur dioxide (SO₂) and nitrogen oxides (NO_x) are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. Nitrogen oxide (NO) and nitrogen dioxide (NO₂) are collectively known as nitrogen oxides (NO_x).

Caesium is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal. Caesium ionizes easily when heated or exposed to light because it is strongly photoelectric (easily loses electrons when struck by light). Cesium 133 is the element most commonly chosen for atomic clocks.

Diamond is harder than graphite because of tetrahedral structure of diamond. In a diamond, the carbon atoms are arranged tetrahedrally. Each carbon atom is attached to four other carbon atoms 1.544 × 10^-10 meter away with a C-C-C bond angle of 109.5 degrees. It is a strong, rigid three-dimensional structure that results in an infinite network of atoms.

When sunlight incident on raindrops formation of a Rainbow occurs in the sky. These raindrops work as a prism. When sunlight hits a raindrop, some of the light is reflected. The electromagnetic spectrum is made of light with many different wavelengths, and each is reflected at a different angle. Thus, spectrum is separated, producing a rainbow.

A simple microscope is a magnifying glass that has a single or double convex lens with a short focal length.

Nuclear reactors operate on the principle of nuclear fission, the process in which a heavy atomic nucleus splits into two smaller fragments. The nuclear fragments are in very excited states and emit neutrons, other subatomic particles, and photons.
