waves (science)

• Types of Waves


  Waves can be classified into two main categories:

  1. Mechanical Waves

  • Need a physical medium (like water or air) to propagate
  • Examples: water waves, sound waves

  1. Electromagnetic Waves

  • Do not require a physical medium
  • Examples: light waves, radio waves, X-rays, gamma rays
  • All are forms of electromagnetic radiation
• Mechanical Waves


  Mechanical waves require a physical medium to propagate. They need a medium to transfer energy from one particle to another. Examples of mechanical waves include:

  • Sound waves
  • Water waves
  • Seismic waves
  • What do you think is the characteristic that distinguishes mechanical waves from electromagnetic waves?
• Electromagnetic Waves


  Electromagnetic waves do not require a physical medium to propagate. They can travel through a vacuum. Examples of electromagnetic waves include:

  • Light waves
  • Radio waves
  • X-rays
  • Gamma rays
  • What are the properties of electromagnetic waves?
• 
  

  Speed (s) = Wavelength (λ) x Frequency (f)
• Wavelength of a Wave


  Wavelength (λ) = Speed (s) / Frequency (f)
• Frequency of a Wave

  Frequency (f) = 1 / Period (T)
• Unit of Speed


  The unit of speed is typically measured in meters per second (m/s)
• Transverse Waves

  Examples: Radio waves, Microwaves, Gamma rays. Key characteristic: particles move at right angles.
• Longitudinal Waves


  Examples: Acoustic waves, Magnetic waves, Ultrasonic waves. Key characteristic: particles move back and forth.
• Longitudinal Waves

  Examples: Sound waves, Seismic waves, Pressure waves
• Transverse Waves

  Examples: Light waves, Water waves, Ripples on a pond
• Longitudinal Waves


  A type of wave where particles move back and forth along the same direction as the wave's propagation.
• Transverse Waves


  A type of wave where particles move perpendicular to the direction of wave propagation.
• This is how you calculate the speed frequency and wavelength using the triangle method.you cover the part you wanna find out and then you do the equation.its either going to be X or ÷
