Waves 76B420C1-D75C-4CCC-A56D-68F6B209325A (Mechanical Waves 6A15B24E…
Waves
Mechanical Waves
disturbance in matter
carries energy
from place to place
3 types of mechanical waves
transfers energy through medium
solids, liquids, and gases = mediums
oscillation of matter
need medium to transfer energy
water waves
seismic waves
sound waves
Electromagnetic Wave
transverse waves
charged particles are accelerated
changing electric & magnetic fields
similar to mechanical waves
carry energy place 2 place
Electromagnetic Radiation
transfer of energy
by electromagnetic waves
waves travel through matter or space = electromagnetic radiation
Difference between Waves
produced = initial energy input
travel = through medium until all energy is transfered
requires medium
can't transmit energy through vacuum
produced = constantly changing fields
travel = through empty space or matter
does not need medium
vibration of charged particles
Types of Mechanical Waves
Transverse Waves
causes medium to vibrate
at right angle
towards travel direction
highest point = crest
lowest point = trough
Longitudinal Waves
vibration of medium = parallel to wave travels
compression = particles close together
rarefaction = particles are spreaded
Surface Waves
travels along a surface
seperating 2 media
similar to transverse wave
Electromagnetic vs Mechanical
