Mrs. Buchanan - Types of Waves

QuestionAnswer
The type of wave in which the particles moves perpendicular to the direction of the wave transverse
The distance between the rest point and the top of a crest or the rest point and the bottom of a trough in a transverse wave amplitude
The distance between one point on a wave and the nearest identical point wavelength
The number of wavelengths that pass a point in a given amount of time frequency
The type of wave in which the particles move in the same direction as the wave compressional
The frequency of a wave is measured in which SI unit? Hertz
The wavelength of a wave is measured in which unit? meters
What causes all types of waves to occur? vibrating objects
Which waves can move through both matter and empty space? Electromagnetic
The density of the compressions and rarefactions in a compressional wave determines which property of the wave? amplitude
A wave hitting a surface and bouncing off is changing direction by which movement? reflection
A wave that moves into a different material, changes speed, and bends through the material is changing direction by which movement? refraction
A wave that hits an obstacle and bends around is changing direction by which movement? diffraction
The law that states that the angle of an incoming wave is equal to the outgoing wave measured from normal Law of Reflection
Objects that have mass, volume, and transfer energy particles
Objects that don't have mass or volume, but transfer energy waves
Sound waves are which type of waves? compressional
What can sound waves travel through? matter
How does the speed of a sound wave change as the density of particles increases? increases
What happens to the speed of a sound wave as temperature increases? increases
A change in the frequency of a wave changes which property of a sound? pitch
A change in the intensity of a sound wave changes which property of a sound? loudness
Which unit is used to measure the loudness of a sound? Decibels
What is the function of the outer ear? collector
What is the function of the middle ear? amplifier
What is the function of the inner ear? Transmits signal to the brain
What can electromagnetic waves travel through? matter and space
How does the speed of an electromagnetic wave change as the density of particles increases? decreases
A change in the intensity of a light wave changes which property of the light? brightness
Which three electromagnetic waves make up the majority of energy given off by the sun? infrared, visible, ultraviolet
An object that reflects a green wavelength appears to be what color? green
An object that reflects all the wavelengths of the visible spectrum appears to be what color? white
An object that absorbs all of the wavelengths in the visible spectrum appears to be what color? black

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
