Sound Waves
The amount of energy that is transferred past a given area of the medium
What is intensity?
The three primary colors of the eye
Red, Green, and Blue
This part of the ear collects sound waves
Outer ear
What does it mean if something is transparent?
Light fully passes through
What is the crest and the trough?
Crest-The highest point of a transverse wave
Trough-The lowest point of a transverse wave
The sensation of frequency
What is pitch?
The three secondary colors of light
Cyan, Yellow, and Magenta
This part of the ear has the action of making impulses to the brain
Inner ear
What does it mean if something is translucent?
Light partly makes it through
What are the two types of waves?
Transverse and Longitudinal
A wave that is a disturbance that is transported through a medium from particle-to-particle
What are mechanical waves?
The colors we see on a certain object
(Hint: What do these colors do that make it so that we see them?)
What is reflection?
This part of the ear has the task of turning sound waves into vibrations
Middle ear
What does it mean if something is opaque?
Light cannot pass through
What type of wave is a sound wave?
Longitudinal wave
Decibels are a unit that measures the amount of energy that is transferred past a given area of the medium
What unit is intensity measured in?
The colors we do not see that are shined on an object
(Hint: What do these colors do so that we do not see them?)
What is absorption? (absorb)
The part of the middle ear that send the movement of the eardrum to the middle ear
Small bones (Ossicles)
Is a thin leaf considered transparent, translucent, or opaque?
Translucent
How do you find the amplitude of a transverse wave?
You find the distance between the rest point and teh crest or trough of the wave
This occurs when the frequency of the applied force is equal to one of the natural frequencies of vibration of the force
What is resonance?
If a shirt is cyan and you know the colors red, green, and blue are being shined onto it, what is happening to each of the colors?
Red-It is being absorbed
Blue-It is being reflected
Green-it is being reflected
How many parts are in the outer ear?
3
What kind of mirror can be considered opaque and translucent?
A one-way mirror
How do you find the speed of a wave?
Speed=wavelength x frequency
