WHAT IS A WAVE? disturbance that transports energy through matter or space

CLASSIFYING WAVES Can it travel through a vacuum (space)? -Electromagnetic -Mechanical How does it move the particles it travels through? -Transverse -Longitudinal -Surface

CAN IT TRAVEL THROUGH A VACUUM? Electromagnetic Wave – YES! oscillating electric and magnetic fields Mechanical Wave – NO! requires a medium

How does it move the particles it travels through? LONGITUDINAL particles in move parallel to the wave

How does it move the particles it travels through? LONGITUDINAL

How does it move the particles it travels through? TRANSVERSE particles move perpendicular to the direction the wave moves

How does it move the particles it travels through? TRANSVERSE

How does it move the particles it travels through? SURFACE WAVES Particles move parallel and perpendicular in a circular motion Boundary between different mediums
