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
