Ignore?
alternating
A type of electricity in which the current flows back and forwards.
Amplitude
The height of the wave, above or below a given reference point.
circuit
The continuous conductive pathway through which electricity can flow.
communication
The process by which a message is sent, received and acted upon.
current
The flow of electric charges through a circuit. It is measured with an ammeter.
electricity
A type of energy that involves the movement of electric charges or the flow of electrons.
gamma
A type of radiation from the electromagnetic spectrum that has the highest frequency.
light
A type of radiation from the visible spectrum that our eyes can detect for sight or used in optic fibres.
longitudinal
A type of wave in which the particles of a medium vibrate in the same direction as the motion of the wave. Sound waves are an example of this.
parallel
A type of circuit in which the components are connected in different pathways.
radiowaves
A type of radiation from the electromagnetic spectrum that has the lowest frequency.
resistance
The opposition to the flow of electric charge in a substance.
series
A type of circuit in which all the components are connected along a single pathway
transformers
A device that can make small voltages larger and large voltages smaller.
ultraviolet
A type of radiation from the electromagnetic spectrum, of higher energy than visible light that can cause cancer.
voltage
The amount of electrical energy lost or gained by an electric charge. It is measured with a voltmeter.
wavelength
The distance between corresponding points on two waves eg. crest to crest or trough to trough.
X-rays
A type of radiation from the electromagnetic spectrum that can be used to view bones of the body.
