The waves

1. What are exactly?

   • Each of the elevations that are formed by disturbing a transmission medium.

2. Types of waves

   • Transverse
     • The transverses move oscillatingly in a direction perpendicular to the spread.
   • Longitudinal
     • longitudinals oscillate in the same direction as propagation.

3. Types of means of transmission

   • Non guided
     • They are those means that transmit the waves by electromagnetic means, that is, without the need for a physical medium or cables.
   • Guided
     • They are those means that transmit the waves by physical means.

4. How can they help us?

   • - Radio and televion waves, which are used in communication.
   • -Microwaves, provide communication paths that replace telephone cables.
   • -Uv rays, which generate tanning.
   • -X-rays, reveal information with a simple photograph.
   • -Infrasonides, for ultrasounds.
