Waves

Waves

1. wave speed, v = frequency, f X wavelenth, lamder

2. v= fxWavelenth

3. period= time for one complete cycle of the waveform

4. transverse waves

   • in transverse waves the medium (in this case the coils ) moves at right angles to the direction of travel

5. longitudinal waves

   • in longitudinal waves the medium (coils) moves in the same way as the direction but close up and then spread out

6. electromagnetic waves

   • increasing frequency ---> radio waves- micro waves - infrared - visible light - ultraviolet - X-rays - gamma rays <----- increasing wavelenth
     • uses
       • microwave
       • gamma= cancer treatment
       • ultraviolet: disco lights and lamps
       • x-Rays= x rays seeing through things

7. richard of york gave battle in vein

   • red, orange, yellow, green, blue, indigo, violet
