TermDefinition
1.Wave a long body of water curling into an arched form and breaking on the shore.
2.Energy power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
3.Amplitude the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
4.Wavelength the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
5.Vibration an oscillation of the parts of a fluid or an elastic solid whose equilibrium has been disturbed, or of an electromagnetic wave.
6.Medium the intervening substance through which impressions are conveyed to the senses or a force acts on objects at a distance.
7.Mechanical Waves an oscillation of matter, and therefore transfers energy through a medium.
8.Frequency the rate at which a vibration occurs that constitutes a wave, either in a material
9.Speed a way of measuring how quickly something is moving or being done, or something moving fast.
10.Crest a point on the wave where the displacement of the medium is at a maximum
11.Trough is the minimum or lowest point in a cycle.
12.Resting Position the position in which the wave would sit if there was no disturbance moving through it.
13.Damping a decreasing of the amplitude of an electrical or mechanical wave.
14.Electromagnetic Waves waves which can travel through the vacuum of outer space.
15.Electromagnetic Spectrum the range of wavelengths or frequencies over which electromagnetic radiation extends.
16.Visible Light a form of electromagnetic radiation
17.Opaque Not reflecting light
18.Primary Colors red, green blue
19.Primary Colors Of Light yellow, black
20.Angle Of Incidence the angle that an incident line or ray makes with a perpendicular to the surface at the point of incidence.
21.Law Of Reflection the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane.
22.Plane Mirror a mirror with a flat reflective surface.
23.Concave Mirror a mirror that is curved inward in the middle
24.Convex Mirror a mirror that is curved outward in the middle
25.Refraction change in direction of any wave.
26.Lens a transparent substance with curved sides
27.Convex Lens is thicker at the centre than at the edges
28.Concave Lens are thinner at the middle

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.
