the entire path that the
object travelled.

3. DESEP

change in displacement.

6. VELOCITY
Refers to the rate of
change in displacement.

7. NAOTECECLRAI
Refers to the rate of
change in speed or
velocity of an object.

8. ACCELERATION
Refers to the rate of
change in speed or
velocity of an object.

9. MIDCETALPENS
Refers to the distance
from the initial to the
final point of an object.

10. DISPLACEMENT
Refers to the distance
from the initial to the
final point of an object.

15. Types and

Waves
Prepared by: Teacher Juhn
Characteristics of Waves

16. What
is a
WAVE?
A wave is a transfer of
energy through a medium
from one point to another.
(Examples: water waves,
sound waves, and radio
waves.)

17. What is
a
medium?
is a matter in which waves
can travel and transfer
energy.

18. two types
of waves
01 Mechanical
02 Electromagnetic

19. Mechanical
WAVES
Waves that require a
medium such as water
waves and sound waves to
travel and transfer energy.

20. electromagnetic
WAVES
Waves that do not require a
medium to travel and
transfer energy.

21. two types
of
MECHANICAL
waves
01 Transverse
02 Longitudinal wave

22. transverse
WAVE
is a wave in which particles
of the medium move
perpendicular to the
direction of the motion of
the waves.

23. Longitudinal
WAVE
is a wave in which the
particles of the medium
vibrate parallel to the
direction of the motion of
the waves.

25. PARTS OF a WAVE

26. PARTS OF a WAVE

27. 01 Crest
02 Trough
03 Resting Point
04 Compression
05 Rarefaction
is the highest point of a wave.
is the lowest point of a wave.
is a point where the coils are close together
or has the maximum density.
is the position that the string would assume
when there is no disturbance moving through it.
is a point in the spring where the coils are
spread out or has minimum density.

28. 1. Wave motion that is parallel to the wave direction is
described as wave.
2. Wave motion that is perpendicular to wave direction
describes a wave.
3. ____ is a kind of wave that does not need a medium.
4. The highest point of a wave is called _____
5. The part of a longitudinal wave where there are fewer
particles is called _____ .
6. A region in a medium of longitudinal wave where
molecules are packed is called .
7. ______is the position that the string would assume
when there is no disturbance moving through it.
8. ______ wave is a type of wave that requires a medium
to transfer energy from one point to another.
