SOUNDS
*from a mere transfer
of energy to the
creation of tunes and
music for
entertainment.
Most of our
gadgets are sound
embedded to
amuse us.
In the field of geology and
oceanography,sound is used to
determine depths.
The health sciences are also using
sound for medical purposes
Some animals are dependent
on sound for movement.
This unit deals with the
propagation of sound through
solid, liquid, and gas. In
the course of discussion, wave
characteristics and properties
particularly reflection and
refraction will be taken into
account.
1.compare the speed of sound through
solids, liquids and gases;
2.infer how the molecular structure of a
material affect speed of sound
moving through it; and
3.investigate the effect of temperature
on speed of sound through fair
testing
a.On which medium does sound
travel fastest? Solid, Liquid, or Gas?
b.How does the temperature of the
medium affect the speed of sound?
c.How are reflection and refraction
manifested in sound?
WORKSHEET 1: Solids, Liquids, and Gases
Direction: Using several
resources and references,
compare the different
characteristics of solids, liquids
and gases by completing the
table below:
CHARACTERISTIC
