Psychical And Chemical Properties

Physical Properties - Any aspect of an object or substance that can be measured without changing it's identity.

5 Examples are Density, color, boiling point, mass and strength.

Chemical Propertiesany quality that can be established only by changing a substance's chemical identity. 

5 Examples are Flammability, Toxicity, pH balance, Heat of combustion and Electronegatvity.

Waves

Wavelength - The distance between repeating points on a wave form of a given frequency.

Wave Frequency - The number of waves to pass a point in a unit of time. 

Wave Height  - The vertical distance between the crest and the preceding trough of a wave.

Waves

Transverse Waves - A moving wave that consists of oscillations occurring perpendicular to the direction of energy transfer. An example is radio waves.

Compressional Waves -  A wave propagated by means of the compression of a fluid, as a sound wave in air is. An example is sound waves.
