Cooperative Learning
(Discuss the instructions and other reminders.)
1. Present a picture of the visible light with corresponding frequencies and
wavelength.
2. Examine the picture and describe the wavelength and frequencies of each
color.
3. Answer the guide questions with your groupmates.
4. Present your output afterwards.

Indicator 1: Modeled effective applications
of content knowledge within and across
curriculum teaching areas
The lesson is related with the lesson in
Science 10. Learning competency: Compare
the relative wavelengths of different forms
of electromagnetic waves S10FE-IIa-b-47
Indicator 5. Exhibited effective practices to
foster learning environments that promote
fairness, respect and care to encourage
learning.
Guide questions:
1.Which color registers the highest frequency?
2. Which color has the shortest wavelength?
3. Which color registers the lowest frequency?
4. Which color has the longest wavelength?
5. Explain the relationship between the wavelength and frequency of light?
B.
Analysis
303543@deped.gov.ph
1. What is the order of colors in order of increasing energies or frequency?
2. How is wavelength and frequency related to the arrangement of colors in
the visible light?
Rubrics is designed to achieve indicator 5.
Using the rubrics, students will be rated
objectively.
Indicator 3: Modeled and supported
colleagues in the proficient use of Mother
Tongue, Filipino and English to improve
teaching and learning, as well as developed
learners’ pride of their language, heritage
and culture.
Indicator 2. Developed and applied effective
teaching strategies to promote critical and
creative thinking as well as other higherorder thinking skills.

Using SOLO framework enhances higher
order thinking skills among students.
Questions 1 is an example of a unistructural
question since it requires one response only,
while question 2 is an example of a relational
question since the response explains the
relationship of wavelength and frequency.
Stress the concepts
Light is one of the electromagnetic waves with a wavelength which can
be perceived by the human eye. It is given off by stars like the sun or other
luminous objects from our surroundings.
Visible spectrum is made up of different colors called as rainbow of
colors such as red, orange, yellow, green, blue, indigo, and violet (an
acronym of ROYGBIV).
Indicator 1: Modeled effective applications
of content knowledge within and across
C. Abstraction
Colors of light or the visible spectrum can be described according to
curriculum teaching areas
their wavelength and frequency.
Through a power point presentation,
The wavelength of light is the distance between corresponding points
discuss visible spectrum its color and intensity
in two adjacent light cycles, and the frequency of light is the number of in terms of wave characteristics
cycles of light that pass a given point in one second. The unit 1 per second
or Hertz (Hz) is the unit of frequency.
W avelength is inversely proportional to frequency of the wave. Waves
with higher frequencies have shorter wavelengths, and lower frequencies
have longer wavelengths. When the frequency of visible light increases, the
wavelength decreases. From the seven colors of light, the red color has the
longest wavelength, but it has the lowest frequency among the light

spectrum. However, the violet color has the shortest wavelength, but it has
the highest frequency. Therefore, the amount of frequency or the
wavelength of light will be determined by its characteristic like color.

1. ______it is part of the electromagnetic spectrum that can be detected by
human eye. 2.______light has the shortest wavelength but highest
frequency in the visible spectrum while (3) __________light has the longest
wavelength and lowest frequency. 4. The wavelength of light is the distance
between corresponding points in two adjacent light cycles, and the
__________ of light is the number of cycles of light that pass a given point
in one second. 5. The wavelength and the frequency of the visible spectrum
are __________ proportional to each other.
Indicator 3: Modeled and supported
colleagues in the proficient use of Mother
Tongue, Filipino and English to improve
teaching and learning, as well as developed
learners’ pride of their language, heritage
and culture.
Using sentence frame helps learners
formulate a comment or a response in
sentence form. The teacher states an
incomplete sentence and the learners will
provide the missing words.
B. List down the colors of the visible spectrum in an increasing frequency but
decreasing wavelength.
