TOC

Electromagnetic Waves - Transverse waves

Require no medium - can travel through vacuumTravel at 3.00 x 108 m/s in a vacuum (else slower)Speed is independent of speed of source/observerRadio, microwave, Infrared, Light, UV, XRay, Gamma Rays are all EM waves. (Cheer)

Types of waves

Mechanical(requiring a medium)

Electromagnetic(need no medium)

Transverse

Longitudinal

S (Shear) Earthquake wavesWaves in guitar stringsSurface waves on water

P (Pressure) Earthquake wavesSound wavesCompression waves in a springSurface waves on water

All EM Waves:Radio, Microwave, IR, Light, UV, X-Ray, Gamma rays

Types of waves

TOC

Longitudinal waves can pass through fluids, Transverse cannot.Only P earthquake waves can pass straight through the earth:

The core of the earth is liquid(Earth is like an egg)P wave

Energy Transport

TOC

Waves transport energy:Sun to earthSound to microphoneEarthquakesMicrowavesOcean wavesDemo - speaker, concentrator
