With a different colored pen...
1) Lable the peak of each upward curve the "crest", the X axis the "resting position", and peak of each downward curve the "trough".
2)Now draw a line from point (15,0) to point (15,25). Lable this line amplitude because from the resting position of each wave to its crest is called the wave's amplitude.
3)Now draw a line from the traugh of one wave to it's crest. Lable this line wave height beacuse from the wave's height to it's crest is it's height.
Remember:
Wave equation: _________________
Speed of light = Wavelength x Frequency
_speed of light=3.00x10^8 m/s
frequency= # of waves/second x 2 waves/sec=2 1/s= 2 hertz= 2 Hz
