Wave Properties. Learning Goals: Define wavelength, frequency, period, and amplitude. Describe the relationship between frequency and wavelength. Explain how a wave’s energy and amplitude are related. Calculate wave speed. Parts of a Wave. Crest: high point of the wave form
Defined - distance between one point on a wave and the nearest point just like it Distance from…
1) Crest to crest2) Trough to trough3) Start of one compression to the next4) Start of one rarefaction to the next
A wave has a frequency of 2 Hz. This means that two wavelengths pass a point in one second. How much time does it take for one wavelength to pass a point?
Answer: 1/2 or 0.5 second, so the period of this wave is 0.5 s.
Answer: 1/3 or 0.33 second, so the period of this wave is 0.33 s.
