Exploring Structures Using Waves

• Ultrasound


  High frequency sound waves used for various applications
• Uses of ultrasound


  • Medical uses
  • Underwater exploration
• Echo sounding


  1. Using high frequency sound waves (including ultrasound)

  2. To find out the depth of the water

  3. To locate objects in deep water
• Waves


  • Have different properties (e.g. speed) depending on the material they're travelling through
  • When a wave arrives at a boundary between materials, it can be completely reflected, partially reflected, continue travelling at a different speed, be refracted, or absorbed
• Studying the properties and paths of waves through structures

  1. Can give clues to some of the properties of the structure that you can't see by eye

  2. Can be done with different waves like ultrasound and seismic waves
