you think these words are?
b. Elicit
Our lesson yesterday was about the Nature of
Electromagnetic Wave.
What are the properties of EM Waves? We have
Three Properties. What are those?
Perfect!
For our next activity, I will give a statement and
then you have to identify if it is TRUE or FALSE.
Are you ready?
1. Most EM waves have the same speed.
2. EM waves travel at the speed of 4x108 m/s.
3. Electromagnetic waves are transverse
waves consisting of changing electric fields
and changing magnetic fields.
Ma’am our lesson yesterday is
about the Nature of
Electromagnetic Wave.
1. They are produced by
accelerated or
oscillating charge.
2. They do not require any
material or medium for
propagation.
3. They travel in free space
at the speed of 3x108
m/s.
Yes Ma’am!
4. Electromagnetic waves transfer energy
through a vacuum.
5. A wave is a disturbance that transfers
energy.

c. ENGAGE
This time, I will be showing to you a short video
clip about electromagnetic spectrum and I have
here the guided questions that you will answer
after watching the video.
1. What makes up electromagnetic waves?
2. What colors makes up the visible light?
3. Which of the electromagnetic waves has
the highest frequency?
4. Which of the electromagnetic waves has
the lowest frequency?
5. Which of the electromagnetic waves has
the longest wavelength?
6. Which of the electromagnetic waves has
the shortest wavelength?
Excellent! All of your answers are correct.
1. Oscillating Magnetic
Field and Electric Field.
2. RED, ORANGE, YELLOW,
GREEN, BLUE, INDIGO,
and VIOLET.
3. Gamma Ray has the
highest frequency
Ma’am.
4. Radio wave has the
lowest frequency
Ma’am.
5. Radio wave has the
longest wavelength
Ma’am.
6. Gamma Ray has the
shortest wavelength
Ma’am.
d. EXPLORE
Now, we will do another activity. I will group you
into three (3) and Group 1 will be TEAM STAR
RADIO, Group 2 will be TEAM AKSYON RADIO, and
lastly Group 3 will be TEAM MOR. Each group will
assign a team leader, secretary, time keeper and
a presenter.
Now, before we start our activity let us be
reminded again with our guidelines in performing
an activity.
TEAM STAR RADIO
1. Respect each other
opinion
2. Be cooperative
3. Finish the activity on time
4. Read the instructions
carefully before doing
the activity
Instructions: Compare the relative wavelengths
and frequency of different forms of
electromagnetic waves by using the picture of
EM Waves.
Team Star Radio will determine
the relative wavelength and
frequency of EM waves by
studying the picture and they
will compare the relative
wavelength and frequency of
EM waves using the table.

TEAM AKSYON RADIO
Instructions: Arrange the EM spectrum in
decreasing wavelength and increasing
frequency. Number each EM wave from 1-7.
Number 1 is the longest wavelength and the
lowest frequency.
___________ visible light
___________ infrared
___________ X ray
___________ radio wave
___________ gamma ray
___________ ultraviolet
___________ microwave
Team Aksyon Radio student will
go in front and they will
arrange the given EM waves in
decreasing wavelength and
increasing frequency.
TEAM MOR
Instructions: Complete the Electromagnetic Spectrum
Chart by arranging the different types of EM waves.
Team MOR will complete the
EM Chart by arranging the
different types of EM Waves.
e. EXPLAIN
Based from your activity, let us see if you we can
answer the following questions.
1. What are the limiting factors that affect
population growth?
2. How does population growth affect the
carrying capacity of an ecosystem?
1. What is the relationship of frequency and
wavelength in the electromagnetic
spectrum?
2. What is the relationship of frequency and
energy in the electromagnetic spectrum?
1. From radio waves to
gamma ray the wavelength
is decreasing. The radio
waves has the longest
wavelength and the
gamma ray has the shortest
wavelength. Also, for their
frequency from radio waves
to gamma ray is increasing.
The radio wave has the
lowest frequency and
gamma ray has the highest
frequency.
2. The frequency and
wavelength in the
electromagnetic spectrum
is inversely proportional. As
one goes up, the other goes
down.
3. The frequency and energy
in the electromagnetic
spectrum is directly
proportional. As on goes up,
the other goes up as well.
f. ELABORATE
Based from your activity, you have learned that
electromagnetic is arranged according to its
wavelength and frequency in what is known as
Electromagnetic Spectrum.
1. What happens to the wavelength of an
electromagnetic wave if its frequency
increases?
Excellent! As frequency increases on the EM
Spectrum, the wavelength decreases. In other
words, wavelength and frequency are inversely
proportional to each other. So, that means radio
waves have the longest wavelengths and
gamma rays have the shortest.
2. How is an electromagnetic spectrum
organized in terms of its frequency and
wavelength?
3. How do electromagnetic waves play an
important role in your life?
4. Which Subject Areas, do you think you can
apply your knowledge about EM Waves?
1. If the frequency of EM
Waves increases the
wavelength decreases.
2. The EM Spectrum is
organized according to
increasing frequency and
decreasing wavelength.
3. Electromagnetic waves
plays an important role in our
daily life. These waves have
many uses which are vital to
our daily lives: visible light
allows us to see; microwaves
and radio waves allow for
long-rang communications via
mobile phones, televisions and
radio, x-rays are used in
medical imaging and many
more.
