There are two main types of waves: mechanical waves, which require a medium like matter or liquid to travel through, such as sound waves, water ripples, and seismic waves; and electromagnetic waves, which do not require a medium and can travel through space, including radio waves, microwaves, infrared, visible light, ultraviolet rays, X-rays, and gamma rays. Mechanical waves can be transverse, with particle displacement perpendicular to propagation, or longitudinal, with particle displacement parallel to propagation.

1. WAVES
Waves are disturbances that travel
through matter or space. There are two
types of waves the mechanical waves
and electromagnetic waves.

2. MECHANICAL WAVES
O Seismic waves travel through the
groundwater ripples and tsunami travel
through water . sound travel trough
solid,liqud,gas.common to all of these is
that they require a medium in order to
travel.As such, they considered as
mechanical waves.

3. ELECTROMAGNETIC WAVES
The waves that travel through space and do
not require a medium are classified as
electromagnetic waves. Examples of these
are radio waves ,microwave , infrared
,visible light , ultraviolet ray ,X ray, and
gamma ray.

4. Trasverse wave
O A mechanical wave where in the direction
of particle displacement is perpendicular
to the direction of wave propagation.

5. O A mechanical wave wherein the direction
of particle displacement is parallel to the
direction of wave propagation.
LONGITUDINAL WAVES
