Waves Flashcards
What is the unit of frequency?
Hertz (Hz)
Frequency definition
Number of waves passing a point each second
Amplitude definition
The furthest point the wave vibrates from the undisturbed position
Wave speed definition
The speed at which the energy is transferred
Oscillation definition
The process of moving back and forth regularly
Examples of transverse waves
- ripples on the surface of water
- any electromagnetic waves
Examples of longitudinal waves
- sound waves
- spring toy
- guitar strings
Longitudinal waves definition
A wave that moves in the same direction in which the particles are vibrating
Wave length definition
The distance from one point of a wave to another
What is the EM spectrum?
R - radio waves
M - microwaves
I - infrared light
V - visible light
U - ultra violet
X - x-rays
G - gamma rays
Formula of wave speed
Wave speed = frequency x wavelength
(M/S) (Hz) (M)
Transverse waves definition
A wave that oscillates perpendicularly to the direction of the waves advance
