Terms in this set (17)
A fundamental quantity that can only be identified in terms of transfers from place to place or transmissions from form to form.
The unit of measurement used to measure energy.
A disturbance that moves through time and space carrying energy.
The substance through which a wave moves.
The point at which a wave is at its maximum upwards value.
The point at which a wave is at its minimum downwards value.
The distance from a point on a wave until it repeats itself on the next wave (corresponding point). E.g. Crest to crest. Unit of measurement: (metre)
The number of waves per second. Unit of measurement: Hertz (Hz)
The maximum height of a wave from its rest position. Unit of measurement: (metre)
The time for a particle to move through one complete wave cycle. Unit of measurement: (second)
A rapid and continuous back and forth up and down movement.
v = f x λ
The relationship between speed, frequency and wavelength to perform simple calculations.
Waves that need a medium to travel in e.g. sound wave, water wave.
To continue through.
Particles in this type of wave travel at right angles to the direction of energy propagation. e.g. electromagnetic radiation (EMR), water
Particles in this type of wave travel back and forth in the same plane as the direction of energy propagation e.g. sound
Electromagnetic radiation (EMR)
Energy that travels as waves and moves at the speed of light. This type of wave does not need a medium in which to propagate/travel through
