What do we call the tops of a transverse wave? Crests
What do we call the bottoms of a transverse wave? Troughs
The height, or distance from rest to crest, or rest to trough is called? Amplitude
The distance from trough to trough or crest to crest is called? Wavelength
The number of waves that pass a point in a second is the waves? Frequency
When a wave bounces back, it has been Reflected
What do we call a reflected sound wave? Echo
What law states that the angle at which the wave hits the surface will be equal to the angle at which the wave bounces off of the surface? Law of Reflection
Which type of mirror makes you look larger? Convex
Which type of mirror makes you look smaller? Concave
Which type of mirror does not make your image larger or smaller? Plane
A wave that has been bent is said to have been Refracted (Refraction)
What causes a wave to bend? Moving through mediums of different densities slows or speeds up a moving wave
As light passes through a prism, it _______, and creates a rainbow Refracts
What describes waves that can pass through a peice of glass? Transmit
An object that blocks all light from passing through it is said to be Opaque
An object that allows all light to pass through it is said to be Transparent
An object that allows only some light to pass through it is said to be Translucent
A piece of glass is: Transparent
A peice of wax paper is: Translucent
A peice of wood is: Opaque
Objects that create their own light are said to be luminous
Objects that do not make their own light, rather they reflect light, are said to be Illuminated

The moon, a human, and a table are: illuminated
Which wave characteristic determines the lights brightness? Amplitude
What colors make up white light? ROY G BIV
Which color of light has the longest wavelength? Red
What determines the color of an opaque object? The color it reflects
Why is a blue shirt blue? reflects blue light
What colors does a black shirt reflect? NONE
What color does a white shirt reflect? ROY G BIV (all)
What determines the color of a transparent object? color it transmits
What do we call transparent objects that only transmits ONE color? Filter

Which electromagnetic wave can be used to diagnose broken bones? X rays
What part of a sound (longitudinal) wave is made up of tightly packed atoms? compression
What part of a sound (longitudinal) wave is made up of atoms spaced far apart? rarefraction
Will sound travel faster through solids, liquids, or gases? Solids
Why does sound move faster through denser matter? Atoms are closer
What wave property controls the pitch of a sound? Frequency
What wave property controls the loudness of a sound? Amplitude
What do we call the sudden change in pitch of a sound as it moves past a still object? Doppler Effect
How many poles do magnets have? 2
What do we call the area around a magnet in which the magnetic forces work? Magnetic Field
Where are magnets the strongest? Poles
Like magnetic poles. . repel
unlike magnetic poles. . . attract
In what direction does electricity always flow? negetive -> positive
What do we call the flow of electrons? electricity
What are three things needed in order to create a circuit? source of electrons, load (something to use electrons) & pathway (wire)
What type of circuit has only one pathway for the electrons to flow? series
What type of circuit has two or more pathways for the electrons to flow? parallel
What do we call the build up of electrons on a surface? static electricity
What creates this build up of electrons? friction
What types of materials allow electrons to flow through them easily? conductors
What types of materials do NOT allow electrons to flow through them easily? insulators
What are two differences between sound and light? 1.Light travels faster than sound2.Sound needs a medium to travel and light does not
What is a complete, closed path through which electric charges can flow? Circuit
How can you re-magnetize a magnet? 1.Stroke it with a strong magnet2.Runing an electric current through it
