TermDefinition
Wave model of light Describes the behaviours of light such as interference and refraction by using the characteristics of waves, wavelength, speed, frequency
Electromagnetic radiation Radiant energy composed of oscillating electric and magnetic fields, or electromagnetic waves, propagated at the speed of light in a vacuum
Electromagnetic Waves Waves produced by an oscillating electric charge resulting in mutually and perpendicular electric and magnetic fields
Electric Charge A physical property of an object that causes it to experience a force when placed in an electromagnetic field
Black body Radiation The radiation emitted by a black body from the conversion of thermal energy, perfectabsorber and emitter of radiation
Photon A quantum of all forms of electromagnetic radiation, a gauge boson responsible for mediating the electromagnetic force
Energy The capacity to do mechanical work, higher content means greater impact when energy is transferred or transformed
Frequency The number of waves that pass a point in one second
Wavelength The distance between corresponding points on successive waves
Threshold Frequency The minimum frequency of a photon that can eject an electron form a surface

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.
