The time of a back and forth swing of the pendulum is called
a period
The measurement of a wave from the resting line to the crest.
Amplitude
EM waves are an example of this type of wave
What is a transverse wave?
If the wavelength is 5 m and the frequency is 5 hz, what is the wave velocity?
V m/s= F Hz X £ m
25 m/s
Visible color light that has the shortest wave length
Blue, indigo, violet end of the rainbow
Every wave, regardless of type or medium, transfers this
What is energy?
The number of wavelengths that pass a given point per second.
What is frequency?
This type of wave vibrates matter in the opposite direction from how the wave is moving.
What is a transverse wave?
The lowest frequency we can hear is about 20 Hz. Calculate the wavelength associated with this frequency for sound that travels at 340 m/s. How long is the wavelength?
V m/s= F Hz X £ m
17 meters

What is the equation to calculate wave speed?
V= wavelength x Frequency
The points where a wave crosses the resting line
Nodes
This type of wave requires a medium and the energy moves in the same direction (parallel) to the medium
