P5 - Light and the EM Spectrum Key Terminology Flashcards
1
Q
Define the term wave
A
a vibration (or oscillation) that transfers energy or information
2
Q
Define the term amplitude
A
the distance from the middle to the top or bottom of a wave (the more energy a wave has, the greater the amplitude)
3
Q
Define the term wavelength
A
the distance from one point on a wave to the same point on the next wave
4
Q
Define the term frequency
A
the number of waves that go past a particular point per second
5
Q
What is a peak?
A
The top of a wave
6
Q
What is a trough?
A
The bottom of a wave
7
Q
Define the term oscillation
A
The repetitive movement that occurs in a back-and-forth motion on both sides of an equilibrium point
8
Q
Define the term longitudinal
A
a wave that moves in the same direction in which the particles are vibrating
- the oscillation is parallel
- along the direction of energy transfer
