14.  Explain the hierarchy of
colors in relation to the
energy of visible light.

MELC

15. define concepts related to
visible light;
rank the colors according to
wavelength, frequency, and
energy.
identify the composition of
electromagnetic spectrum; and
conduct a simple experiment to
describe visible light.

OBJECTIVES

16. 16
Frequency

17.  The energy of the
colors of light
increases as one
goes towards the
right side of the
color spectrum and
red light has the
least energy and
blue light has the
most energy
17

19. Light
 composed of colors of different and
wavelength
 exhibits the characteristics and
properties of a wave
 Arrangement of colors of light
shows the order of color’s
corresponding energy.
19

20. ROYGBIV
 Only part of the
spectrum that can be
seen by the naked
eye
20

21. Refraction
 the bending of light when it travels
from one medium to another of
different optical densities
21

22. REFRACTION
 RED – refracted the least
 VIOLET – refracted the most

25. Dispersion
 a special kind of refraction
which provided us colors of
light.
 observed when white light
passes through a triangular
prism.
 When white light enters a
prism, separation into
different colors is observed.
25

26. REMEMBER!
 Light is composed of colors of light of
different frequencies and wavelength
 The frequencies of the colors of light
are inversely proportional the
wavelength
 The arrangement of colors of light
shows the hierarchy of the color of
light’s corresponding energy
26

27.  White light is made up of many
different colors of light and each
of these colors of light bends
differently
