<span>The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths.</span>
The correct answer is the option A which is radio waves, microwaves, visible light, x-rays.
Explanation:
Electromagnetic spectrum is the graph describing the ranges of frequencies of different electromagnetic waves.
As frequency and wavelength are inversely proportional.
The waves with long wavelength have low frequency and waves with short wavelength have high frequency.
Rdiowaves have long wave length and low frequency and microwaves have frequency more than radio waves and visible waves have high but x rays have of frequency of all given in list.
Hence on the bases of frequency:
Radio waves ≤ Micro waves ≤ Visible waves ≤ x-rays
Cadmium is a chemical element with atomic number 48 which means there are 48 protons and 48 electrons in the atomic structure. The chemical symbol for Cadmium is Cd.
Solutions are made up of two non reacting species called solute and solvent. The amount of solute in solvent is known as concentration of that solute. Concentration is often measured in Molarity. Molarity is the amount of solute dissolved in 1 dm3 of solution. Answer to your question is as follow;
