Waves

Wave Motion Watch the video and then answer the questions that follow. 1. Vocabulary Matching Match the vocabulary term with the correct definition. Frequency The number of complete waves that pass a fixed point in a given time. Amplitude The distance from the maximum disturbance to the undisturbed position. Wavelength The distance between a point on one wave and the same point on the next wave. Period The time for one complete cycle. 3. How is the wavelength of a transverse wave measured? Crest to crest or trough to trough From beginning to end From middle of one compression to the start of the next. Both A and B 4. Write "high" or "low" to describe the amplitudes of each wave. high low 6. How many waves are in this picture? 3 4 4.5 8 Labeling a Wave Label the blue dots with the correct terms. amplitude, crest, trough, wavelength amplitude wavelength crest trough
