Light and its Interactions with Matter

light wave transverse electromagnetic waves that can but do not require a medium (matter—solid
transmission a wave passing through an object or through empty space with no disturbance (in a straight line
absorption when a wave is taken in (absorbed)
reflection when a wave is bounced off an object
refraction the bending or scattering of waves
diffusion scattering of waves in all directions
diffraction The bending of a wave as it moves around an obstacle or passes through a narrow opening
dispersion The separating/scattering of a wave into its different frequencies (such as colors in a prism)
electromagnetic spectrum a range of waves that can travel through matter or empty space and is related to electric and magnetic fields (includes visible light--colors)
visible light wavelengths on the electromagnetic spectrum in the colors of the rainbow (ROYGBIV) shorter than infrared but longer than ultraviolet. Red=longest
Transparent material that allows light to be transmitted in a straight line
Translucent material that refracts light
Opaque material that may absorb or reflect light
independent variable the one factor that is changed (manipulated) by the experimenter (cause)
dependent variable The outcome factor (result); the variable that may change in response to manipulation of the independent variable.(effect)

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.
