Waves Mind Map
Mechanical Waves
Properties
Frequency and Period
repeats at regular time intervals
a wave's frequency
equals the frequency of the vibrating source
Wavelength
increasing frequency decreases wavelength
Wave Speed
Speed=Wavelength*Frequency
Amplitude
maximum displacement of medium
Types of Waves
Transverse Waves
shaking a rope
causes medium to vibrate
at right angles
up and down motion
Longitudinal Waves
vibration is parrelel
to the direction of the wave
occurs in soundwaves
occurs in P waves
that are produced by earthquakes
Surface Waves
Ocean Waves
combination of transverse and longitudinal
Definition
disturbance in matter
that carries energy
from one place to another
Electromagnetic Waves
Definition
transverse waves
consisting of changing electric fields
and changing magnetic fields
How they are Produced
by electric charges that accelerate
How they travel
in forms of waves
can travel through empty space
