| Which type of wave moves the matter left to right as it passes by? | Longitidinal Waves |
| Which type of wave carries sound energy? | Longitudinal Waves |
| Which type of wave carries light energy? | Transverse Waves |
| Which type of wave carries the energies found on the electromagnetic spectrum? | Transverse Waves |
| What is a medium? | Matter |
| Which wave must have a medium in order to carry energy from place to place? | Longitudinal Waves |
| 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 sun, a lightbulb and a fire are | luminous |
| 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 carries the most energy? | Gamma waves |
| 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 |
