1 Types of Waves Foldable

2 Foldable Directions 2x2 Foldable Definitions on the flap
Example waves in the middle

3 Electromagnetic Waves
Waves which can travel through the vacuum of outer space; no medium needed Ex. Light waves, X-rays, Radio waves An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 10^8 m/s

4 Electromagnetic Spectrum

5 Sound Waves Mechanical wave
Typically, this medium is air At the source, there’s some vibrating object capable of disturbing the first particle of the medium Transported from one location to another by means of particle-to- particle interaction Longitudinal wave

6 Seismic Waves Waves of energy caused by the sudden breaking of rock within the earth or an explosion Two types Body waves travel through the earth's inner layers Surface waves can only move along the surface of the planet like ripples on water

7 Body Waves P-waves S-waves Fastest kind of seismic wave
The first to 'arrive' Can move through solid rock and fluids, like water or the liquid layers of the earth. Pushes and pulls the rock it moves through just like sound waves push and pull the air S-waves Second wave you feel Can only move through solid rock, not through any liquid medium. S-waves move rock particles up and down, or side-to-side--perpendicular to the direction that the wave is traveling in

8 Body Waves cont’d.

9 Surface Waves Love waves Rayleigh Waves
Named after A.E.H. Love, a British mathematician who worked out the mathematical model for this kind of wave in 1911 Fastest surface wave and moves the ground from side-to-side Confined to the surface of the crust; Love waves produce entirely horizontal motion Rayleigh Waves Named for John William Strutt, Lord Rayleigh, who mathematically predicted the existence of this kind of wave in 1885 It moves the ground up and down, and side-to-side in the same direction that the wave is moving. Most of the shaking felt from an earthquake is due to the Rayleigh wave, which can be much larger than the other waves

10 Surface Waves cont’d.

11 Water Waves Combination of both longitudinal and transverse motions
The particles travel in clockwise circles The radius of the circles decreases as the depth into the water increases

Waves, Sound and Light. WHAT ARE WAVES? A wave is a disturbance that transfers energy (not matter) from place to place. People jump up and down, moving.
