3. 3.
4. 4.
5. 5.

4. ELECTROMAGNETIC WAVES Vs. MAGNETIC WAVES

5. Activity 3
Mechanical Waves
Vs.
Electromagnetic Waves (How
do waves propagate?)

6. A. What are mechanical
waves? (Reflect on Activity1)
*Transverse=
*Longitudinal=
*Surface Waves=
Mechanical Waves
(With Medium)

7. B. What are the types of electromagnetic
waves? (Reflect on Spectrum Chart)

*
Electromagnetic Waves
(Without Medium)

8. Q1. What is the difference
between mechanical waves
and electromagnetic waves
based on the Activity 1?

9. Q2. What are the
examples of medium
we can use to
propagate waves?

10. Q3. What is the difference
between mechanical waves
and electromagnetic waves
based on the Activity 3?

11. Q4. What are the
7 Types of
Electromagnetic
Waves?

14. Application:
*What kind of
electromagnetic waves do
we have in our mobile
phone?

15. Application:
*How important waves
are in our daily lives?

16. Generalization:
*How mechanical and
electromagnetic waves
differ?

17. Assessment:
-True or False-
Write JOY if the statement is
True; and CHICKEN if the
statement is False.

18. 1. Sunlight is an
example of
mechanical wave.

19. 2. Earthquake is an
example of
mechanical wave.

20. 3. Electromagnetic
waves required
medium to
propagate.

21. 4. Mechanical waves
do not required
medium to
propagate.

22. 5. Waves emitted by
our mobile phone is
known as “radio
waves”.

23. ASSIGNMENT: Bring art materials for “Sounding
Box” making. (Box, Rubber bond,scissors,stickers)
