The Physics of Color
Plants look green because they reflect Green Light
How we see Color
geometry in nature
Hydrogen Bond- a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
Polar Covalent Bond- A covalent bond, also called a molecular bond, is a
chemical bond that involves the sharing of electron pairs between atoms.
Surface Tension- the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer
Capillary action: Capillary action describes the spontaneous flow of a liquid into a narrow tube or porous material. This movement does not require the force of gravity to occur. In fact, it often acts in opposition to gravity.
Capillary Action Activity:
Refraction: is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.
Reflection: the throwing back by a body or surface of light, heat, or sound without absorbing it.
Electromagnetic Spectrum: the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies.
Visible Range: The visible spectrum is the portion of theelectromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to 740 nanometers.
