Waves
electromagnetic waves
magnetic field
a region of space that produces magnetic forces
electric field
electromagnetic waves
transverse waves that consist of changing magnetic fields and electric fields
can travel through empty/vacuum space and matter
called electromagnetic radiation
exerts electric force on charged particles
produced by electrically charged particles and changing magnetic fields
differences between mechanical
and electromagnetic waves
mechanical cannot transfer energy through empty/vacuum space
mechanical requires medium
electromagnetic can transfer energy through empty/vacuum space as well as solid/liquid matter
types of mechanical waves
transverse
highest point above rest point is
crest
lowest point is below rest point is
trough
rest point
is when object is not moving
wave that causes medium to
vibrate at
right angles
in which the wave travels
up and down
longitudinal
vibration of medium is
parallel
to direction the wave travels
compression
area where particles in a medium are close together
rarefaction
area where particles in a medium are spread out
surface
wave that travels along
surface
in between two media
characteristics of
both **
longitudinal and
transverse
waves
properties of mechanical waves
#
#
amplitude
height
in meters
wavelength
distance
between two wavelengths
that are
next to
each other
period
time
it takes for a complete wave
to pass a certain point in seconds
frequency
high
low
mechanical wave
created when source of energy :bulb:
cause vibration to travel through a material
gradually loses energy
uses matter to transfer energy
ex: ripples in puddle
