What Are Four Uses of A Radio Wave

  1. To listen to music on AM or FM radio stations
  2. Cell phone communications
  3. VLA telescope (Very Large Array) to make clearer radio image
  4. Carry signals for cable televisions

What Is The Wavelength Range And Frequency Range

  • Frequency Range: <3x10" Hz
  • Wavelength Range: >1mm

Description of Technology

Used to detect subtle changes in brain pressure and/or heart pulse waving monitor. Made by placing a thin layer of designed rubber between two strips of copper. The copper strips act like radio antennas. It involves radio waves at the antenna and rubber sandwich. Radio waves reflected by the antenna slows down in frequency. When the pressure is relaxed, the antennas move apart and the radio waves speeds up.

Material Involved

Simple machine made by placing a thin layer of designed rubber between two strips of copper. The copper strips act like radio antennas. The rubber serves as an insulator.

Impact of New technology

The impact is the device is able to read the impulse of another person without touching them or heart pulse monitor. In the short run they hope it'll be able to track packages and monitor health conditions. Also the impact is hopefully it can determine blood circulation to see if you have any problems and help to see what there is that can be done
