  • Light
    An electromagnetic wave
  • Electromagnetic waves
    • Do not require a medium for transmission
    • Energy is transferred through radiation
  • Medium
    A physical substance through which energy can be transferred
  • Radiation
    A method of energy transmission that does not require a medium
  • Wavelength
    The distance from one crest to the next
  • Electromagnetic waves carry both electric and magnetic parts
  • In a vacuum the wave travels at the speed of light, 3.00 * 10 ^ 8 m / s
  • Electromagnetic wave types
    • Radio waves
    • Microwaves
    • Visible light
    • X-rays
    • Gamma rays
  • Classification of waves
    Classification of ways by their energy levels
  • Visible light is a small range of the entire spectrum
  • Visible light
    Electromagnetic waves that the human eye detects
  • Colors of visible light
    • Red
    • Orange
    • Yellow
    • Green
    • Blue
    • Indigo
    • Violet
  • White light
    Made up of all the colors of light in the visible spectrum
  • Light production
    1. Atoms within a material absorb some form of energy
    2. Electrons become excited and jump to a higher energy level
    3. When the electron returns to the original energy level they release energy in the form of a photon (light)
  • Sources of light
    • Sun
    • Incandescence
    • Electric discharge
    • Fluorescence
    • Phosphorescence
    • Chemiluminescence
    • Bioluminescence
    • Triboluminescence
    • LED lights
  • Incandescence
    When materials such as metals are heated to a high temperature they begin to glow, starting red and transitioning to orange, yellow, white, and then bluish white
  • Electric discharge
    When an electrical current passes through a gas, light is produced
  • Phosphorescence
    Phosphorus absorb light at a high energy and release visible light at a lower energy
  • Fluorescence
    When an object absorbs ultraviolet light and immediately releases the energy as visible light
  • Chemiluminescence
    A chemical reaction can result in the production of light/energy, typically with no heat produced
  • Bioluminescence
    Chemiluminescence occurring in a living organism
  • Triboluminescence
    When certain types of crystals are scraped or banged together, sparks are produced
  • Light emitting diodes (LEDs)

    A type of electrical switch made from semiconductor materials such as silicon, that only flow in one direction
  • Light travels in a straight line
  • Incident light

    Light emitted from a source
  • Virtual image
    An image formed by light coming from an apparent light source, where the image is formed by rays that do not come from the location of the image
  • Concave mirror
    Reflection is from the inner surface of the spherical section
  • Convex mirror
    Reflection is from the outer surface of the spherical section
  • Physical change
    Reversible change that does not create a new substance
  • Chemical change

    Irreversible change that creates at least one new substance
  • Physical property

    Something that can be observed without a new object forming
  • Qualitative property
    Physical property that involves the five senses
  • Quantitative property
    Physical property that involves numbers
  • Chemical property
    Description of how two substances interact
  • Diatomic elements

    Two of the same elements combined
  • Proton
    Positively charged and in the nucleus
  • Neutron
    Neutral and in the nucleus
  • Electron
    Negative in the orbit
  • In an atom the number of protons and neutrons are the same
  • All atoms want to become stable
