T2: Waves and I.T.

Topic 2 vocabulary and other important terms

TermDefinition
Electric Circuit a complete, unbroken path that electric charges can flow through
Voltage the difference in electric potential energy per charge between 2 points in a circuit
Resistance a measure of how difficult it is for current to flow
Diameter distance across a circle through the midpoint
Ohm's Law resistance in a circuit is equal to voltage divided by current
Series Circuit all parts of a circuit are connected one after another along one path
Parallel Circuit different parts of a circuit are on separate branches meaning there are several paths for current to travel
Wave any disturbance that transfers energy from one place to another
Mechanical Wave waves that result from a vibration of a medium
Transverse Wave motion of the wave is perpendicular to the motion of the medium through which the wave travels
Longitudinal Wave a wave that travels in the same direction as the vibration that produced the wave
Cyclical a repeating series of events
Amplitude measures the distance from the resting point of the wave and the crest
Wavelength measures the distance between 2 identical parts of the wave
Frequency measures the number of times a waves repeats over a period of time
Electronic Signal information that is sent as a pattern in a controlled flow of current through a circuit
Wave Pulse a pulse of energy that travels through a circuit
Electromagnetic Signal information that is sent as patterns of electromagnetic waves
Analog Signal allows for a continuous record of some kind of signal
Digital Signal allows for a record of numerical values of an action at a set continuous time intervals
Binary Signals consists of ones and zeros
Transmission moving
Pixels small uniform shapes that are combined to make a larger image
Information Technology consists of computer and telecommunications
Software refers to programs that encode, decode, and interpret information

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.
