Introduction
A mechanical wave
transfers (time varying)
Kinetic Energy without
a net transfer of
matter.
Mechanical waves
require a physical
medium through/on
which to propagate e.g.
sound/ocean waves

Introduction
An electromagnetic
wave transfers Energy
between charged
particles.
Electromagnetic waves
can move through
physical media (e.g.
glass) but do not rely
on it, since even a
vacuum (space) has
magnetic and electric
properties.

Transverse




Direction of wave
oscillation is
PERPENDICULAR to the
direction of wave
travel. e.g
electromagnetic waves,
S waves in
earthquakes, surface
ocean waves.

Longitudinal




Direction of wave
oscillation is PARALLEL
to the direction of wave
travel. e.g sound, P
waves in earthquakes.

Wavefront




Wavefront ­ a line
joining all points on the
surface of a wave which
are IN PHASE (in step
with each other)

Wavelength




Wavelength ­ the
shortest distance
between two
wavefronts with
identical phase.

Period




Period T (s) ­ the
shortest time interval
between two
wavefronts with
identical phase.

(or waves passing a
fixed point) every
second.
