is a disturbance or oscillation that
travels through matter or space, accompanied
by a transfer of energy.
wave
is one in disturbance occurs perpendicular which the to the direction of travel of the wave. (Light)
transverse wave
is one in which the disturbance occurs parallel to the line of travel of the wave. (Sound)
longitudinal wave
is a wave whose displacement has a periodic variation with time or distance, or both.
longitudinal wave
he showed that two fields
fluctuating together can form a propagating electromagnetic wave.
Scottish physicist James Clerk
Maxwell (1831–1879)
▪Electromagnetic wave is a ______ with the
electric and magnetic fields both perpendicular to
the direction in which the wave travels.
transverse wave
Electromagnetic waves can travel through a vacuum
or a material substance, since electric and magnetic
fields can exist in either one.
