Transverse waves are known as:ELECTROMAGNETIC WAVES
-Visible light-Gamma rays-Microwaves-Radio waves
-X rays
Longitudinal Wave
____________ parts of the wave.
_________ parts of the wave.

Longitudinal waves are known as:
How do sound waves travel?
SOUND WAVES
Sound is produced by vibrations in a medium.
What is a MEDIUM?A substance that a wave travels
through!What are the 3 mediums that
sound can travel through?1. SOLID 2. LIQUID 3. GAS
What is the BEST medium for transferring sound waves?
SOLID
Since its molecules are tightly packed together, they can transfer
the energy easily and quickly!
Amplitude:how large a wave is
Wavelength:how long a wave is, from crest
to crest
Frequency:The number of waves produced
in a certain amount of time.
Period = Frequency/TimeSound waves are produced by a
guitar and 16 waves are measured in 2 seconds. What is
the period?
Period= 16 waves/2 seconds
Period= 8 waves/sec.
Pitch vs. LoudnessThe PITCH of a sound is
determined by the frequency of a sound wave.
Pitch vs. LoudnessThe LOUDNESS of a sound is
determined by the amplitude of a sound wave.
What is the Doppler Effect?The sound waves IN FRONT of the object are packed together and
loud, while the waves BEHIND the object are stretched out and quiet!
Reflection:The bouncing back of a wave after
it strikes a barrier.
Diffraction:The bending of waves around
barriers and through openings.
Interference:The result of two or more waves
overlapping.
Resonance:Occurs when an object vibrating
causes a second object to vibrate.
Refraction:The bending of a wave as it passes
at an angle from one medium to another.
Absorption:The transfer of energy carried by light waves to particles of
matter. Example:-Greenhouse-wearing dark
colors
