Physics & Chemistry Flashcards
1
Q
Define the term periodic time
A
A motion that repeats itself regularly.
2
Q
Define the term speed
A
The rate at which someone or something moves or operates.
3
Q
Define the term wavelength
A
The distance between two consecutive points on a wave.
4
Q
Define the term frequency
A
The rate at which a wave oscillates over a period of time.
5
Q
Define the term amplitude
A
The maximum extent of an oscillation, measured from the point of equilibrium.
6
Q
Define the term oscillation
A
Movement back and forth in a regular rhythm.
7
Q
What is the formula relating time period & frequency? (include units)
A
Frequency = 1/time period. Units = Hz.
8
Q
What is the formula for wave speed? (include units)
A
Wave speed = wavelength * frequency. Units = M/s
