Waves are disturbances that transfer energy from one place to another without transferring matter. There are two main types of waves: mechanical waves, which need a medium to travel and can be transverse or longitudinal; and electromagnetic waves, which can travel through a vacuum. Key parts of a wave include the crest, trough, amplitude, and wavelength. The wavelength is the distance between crests or troughs, while the amplitude is half the distance between crest and trough. Frequency refers to how often a vibration occurs.

1. Waves

2. Wave
-a wave is a disturbance that moves energy from
one place to another
-they transport energy from one point to another
without transferring matter.
-example: As the waves get
through, the rubber duck in
the tub moves up and down.
When the wave disappears,
it is back at its original position.

3. Types of Waves
1. MECHANICAL WAVES
-these types of waves need a medium to be
transmitted
-they have to travel
through a matter as the
molecules in the medium
collide thereby passing on
the energy
-example: sound wave

2. ELECTROMAGNETIC WAVES
-these types of waves can travel through a
vacuum (empty space)
-they don’t need a
medium
-examples:
electromagnetic waves
in the electromagnetic
spectrum

3. TRANSVERSE WAVES
-the direction of the particles is perpendicular
(90° angle) to the direction of the wave,
examples: sea waves and light waves
-think of the wave moving from left to right,
while the particles
move up and down
-example: the rope
moves up and down
as the wave passes
through it

6. Types of Waves
4. LONGITUDINAL WAVES
-the particles move in the same direction of the
wave, examples: sound waves and seismic waves
-example: If the portion of the spring is
compressed and then let go, the wave will move
left to right.
At the same time,
the coils of the
spring will also
move left to right.

4. LONGITUDINAL WAVES
-Compression: the part where the particles are
compressed
-Rarefaction: the part where particles are spread out
or stretched
