Waves

• Wave - temporary disturbance or oscillation.
• oscillation means "vibration"
• Mechanical Wave - needs a source and a medium to propagate

  Waves in Solid

  Waves in Liquid

  Waves in Sound
• C - Crest

  H - Height

  E - Equilibrium

  W - Wavelength

  F - Frequency

  A - Amplitude

  T - Trough
• Crest - highest point
• Height - distance between crest and trough and vise versa
• Equilibrium - resting position
• Wavelength - distance between two crests/ two troughs
• Frequency - amount of waves
• Amplitude - equilibrium to crest/trough
• Trough - lowest point
• F - Frequency

  E - Energy

  W - Wavelength

  S - Speed
• Frequency vs Wavelength - Inversely proportional
• Frequency vs Energy - Directly Proportional
• Wavelength vs Energy - Inversely Proportional
• Speed - constant (3 x 10⁸)
• Electromagnetic wave - requires source but doesn't need a medium.
• Electromagnetic waves are produced by ELectricity and Magnetism.
• EM Spectrum - Radio, Microwave, Infrared, Visible Light, Ultraviolet, X-ray, Gamma.

• Radio Waves - longest of all but lowest frequency. (Hertz)
• Microwave - higher frequency and energy than radio. (Maxwell)
• Infrared Waves - Most often exposed to. (Body Heat) (Sir Herschel)
• Visible Light (Optical Spectrum) - is visible to humans.

  (ROYGBV)
• Ultraviolet - higher energy than light waves. Can cause skin problems. (Ritter)
• X ray (Roentgen Rays) - extremely high energy, used for imaging bone structure. (Roentgen)
• Gamma Rays - greatest energy and highest frequency. (Lightning and Nuclear explosions) (Villard)
