Worksheet. Students will define wave and differentiate transverse and compressional (longitudinal). Illustrate and label the parts of a transverse wave using the terms, trough, crest, wavelength, and amplitude. Discuss how distances between crests affect the wavelength. Hypothesize how wave energy is proportional to the frequency. Evaluate why electromagnetic waves do not need a medium to transfer energy.
Answer Key included. Check out my power point Middle School Physical Science 4-1 Waves and Their Applications in Technologies for Information Transfer as a resource on TPT.
Can be edited for younger or older students.
