ACTIVITY 1: “WHAT ARE THE TYPES OF THE
WAVES?”
ACTIVITY 2: “WHAT ARE THE PARTS OF THE
WAVES?”
A wave is a periodic disturbance that moves away from a
source and carries energy with it. Transverse, longitudinal,
and surface waves are types of mechanical wave.
The different types of waves are distinguished according to the
direction of vibration of particles with respect to the direction in
which the wave travels.
Directions: Distinguish the following types of waves as transverse,
longitudinal, surface, mechanical, and electromagnetic wave.
1.
Waves in a rope are
called______________ waves because
the individual segments of the rope
vibrate perpendicular to the direction in
which the waves travel.
2.
When each portion of coil spring is
alternately compressed and extended,
_______________waves are produced.
3.
________________waves are
combination of transverse and
longitudinal waves.
4.
Waves that require a medium for wave
propagation are called
________________.
5.
__________________waves don’t
require a medium for propagation.
Directions : Identify the parts of the wave. Choose your answer from the box
below.

Trough
compression
Transverse Wave
________________1. The highest point of the wave ( points A, E, H)
________________2. The lowest point of the wave (points C, J)
________________3. The maximum displacement that the wave
moves away from its equilibrium position. (point A to dotted lines)
________________4. The distance between adjacent crests or
troughs. (points A to E or E to H)
_________________5. The dotted lines in the wave.
B. Longitudinal Wave
________________1. The parts where the coils are pressed together.
________________2. The parts where the coils are spread out.

ACTIVITY 1: “HOW DO YOU DESCRIBE WAVES?”
Directions: Compute the frequency and wave speed. Record them in Table 2.
Table 2. The speed of a wave.
Crest, trough, amplitude, frequency, wavelength, period, wave
speed are important terms and quantities used to describe
periodic waves.
