Waves

Master waves! This worksheet covers types, properties, and vocabulary for grades 6-8.

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. 2. Which type of wave is this? Transverse Longitudinal Both Neither 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 high low 5. How is the wavelength of a longitudinal wave measured? Crest to crest or trough to trough From beginning to end From middle of one compression to the middle of the next. Both A and B 6. How many waves are in this picture? 3 4 4.5 8 Transverse and Longitudinal Waves Watch the video and then answer the questions that follow. 7. Which type of wave is this? Transverse Longitudinal Both Neither 8. Sort the characteristics under each type of wave. Transverse Waves Travel perpendicular to the medium Ocean wave is an example crest and trough Longitudinal Waves An example is sound Travel parallel to the medium compression and rarefaction Electromagnetic Waves light is an example Don't require a medium
