Science Unit 3 (waves) - Coggle Diagram

- - - - In a mechanical wave, the wave travels because the waves only vibrate the matter, therefore passing the disturbance.
  - - - Longitudinal waves are waves in which the vibration of the medium is parallel to the direction the wave travels.
      - Examples
        
        Sound waves
    - - transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance.
      - Examples
        
        Light waves
        
        Radio waves
    - - Mechanical waves are waves that need a medium to travel through
        
        A medium is made of things that can interact with each other.
        
        Examples
        
        Air molecules
        
        Water molecules

      - Examples
        
        Sound waves
        
        Water waves
        
        Seismic waves
- - - - Constructive
        
        A constructive interference is when two waves create a larger wave.
      - Destructive
        
        Destructive interference is when two waves cancel each other out
  - - - The wavelength is the distance between 2 identical points.
    - - We compare the measurements of the two waves
    - - Frequency is the amount of waves in a specific timeframe
    - - The amplitude is the distance between the maximum displacement of the medium and the starting point.
- - - - Red

  - - - Pupil
        
        The part of the eye parts taking in light. Light is measured by the iris,
      - Iris
        
        The iris measures light by expanding or contracting. located in front of the pupil
      - Lens
        
        The lens focuses the light by being stretched and compressed by muscles.
      - Cornea
        
        Focuses the light into the eye.
      - Optic nerve
        
        Sends the image as electrical signals to the brain.
- - - - The pitch of sounds is determined by the frequency of vibration of the sound waves that produce them. Sound waves with a high frequency produce high-pitched noises, whereas sound waves with a low frequency produce low-pitched sounds.
    - - he amplitude of a sound wave determines its loudness or volume. Measured in decibels (db)
  - - - The human ear works because of all the parts in it.
