1. A rainbow projects the spectrum of white light from red to violet in top-to-bottom order. 2. Wavenumber is the count of waves per unit of time. 3. For every excitation of a molecule, there is always a corresponding emission of luminescence. 4. In an absorption plot, the wavelength determines the probability of a transition. 5. Glucose is prone to n + n* transition. 6. Halides and halogens affect the absorption band of a material in a phenomenon called halochromism. 7. UV-vis absorption of metal complexes is caused by the energy gap between the HOMO and LUMO of the metal ion. 8. Stray light increases the number of photons reaching the detector. 9. Transmission is inversely proportional to absorptivity. 10. A He-Ne laser is a continuum source.

States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
