Parts of a Wave

.

Part 1

 

In the diagram below, identify the parts of a wave and then give a definition of each term

.

Crest / trough / line of origin / wavelength / amplitude 

 

crest = 5 (  the highest point of the wave)               
trough = 2 (the lowest point of the wave)   
line of origin= 1 (mean position of the particles)     
wavelength= 3 (The distance between one point on a wave and the same place on the next wave)
amplitude=4 (The distance between the crest or the trough and the line of origin)

Part 2

 

State which of the following waves you think has the highest frequency and which might have the lowest frequency. Explain the reasons for your selections.

wave #	crest	Trough	wavelength
1	1 cm	1 cm	2 cm
2	3.5 cm	3.5 cm	2.5 cm
3	.5 cm	.5 cm	3 cm
4	2 cm	2cm	.5 cm

(Perhaps it would be useful for you to draw, on graph paper, the four different waves )

The highest frequency is the Wave number 1 and the lowest frequency is the wave number 4, because the frequency and wavelength are inversely proportional.
