# Waves

the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced. diffraction
he fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density. refraction
A plucked guitar string is a simple example of a standing wave. A plucked string emits a particular sound frequency depending on the string length and how taut or dense the string is. standing wave
the throwing back by a body or surface of light, heat, or sound without absorbing it. "the reflection of light" reflection
occurs when the maxima of two waves add together the two waves are in phase, so that the amplitude of the resulting wave is equal to the sum of the individual amplitude. constructive interference
occurs when waves come together so that they completely cancel each other out. When two waves destructively interfere, they must have the same amplitude in opposite directions. destructive interference
every charge in space creates an electric field at point independent of the presence of other charges in that medium. The resultant electric field is a vector sum of the electric field due to individual charges. principle of superposition
sounds produced by the combination of two waves with almost the same frequencies. Wave beats are caused by wave interference. beats
the net effect of the combination of two or more wave trains moving on intersecting or coincident paths. The effect is that of the addition of the amplitudes of the individual waves at each point affected by more than one wave. interference
a point along a standing wave where the wave has minimum amplitude. For instance, in a vibrating guitar string, the ends of the string are? nodes

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
