Explanation:
Atoms are considered as the basic unit of matter because atoms combine to form matter. Atoms combine to form elements and compounds which further make up the atom.
Atoms contain electron, proton and neutrons. Electrons are negatively charged particles. They do not combine to form matter. A stable atom is a combination of fixed number of electrons, protons and neutrons.

The best solution to deforestation is to curb the felling of trees by enforcing a series of rules and laws to govern it. Deforestation in the current scenario may have reduced; however, it would be too early to assume. The money-churner nature of forest resources can be tempting enough for deforestation to continue.

Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, waves from lowest frequency to highest frequency are radio waves, infrared rays, ultraviolet rays and gamma rays.
Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.
There is a relation between energy of wave. frequency of wave, and wavelength of wave
Mathematically,
E=hc/λ
where,
E = energy of electromagnetic wave
h is planks constant having value 6.67×10⁻³⁴js
c is speed of light that is 3×10⁸m/s
λ is the wavelength of electromagnetic wave
Waves from lowest frequency to highest frequency are radio waves, infrared rays, ultraviolet rays and gamma rays.
Therefore, waves from lowest frequency to highest frequency are radio waves, infrared rays, ultraviolet rays and gamma rays.
