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
