The material may move some, but it wants to come back to its original state. Example: slinky Kinds of Waves 1. Compression 2. Transverse 3. Surface . orsion 4. Torsion Compression vs. Shear Waves s Compression (Longitudinal) Come from compressing atoms close together and pulling them apart Can travel through any material state s Shear (Transverse) Come from pulling an atom perpendicular to the bonds holding it to other atoms Requires rigid bonds Only travels through solids Wave Properties 1. Wavelength s The distance between wave crests Shear Compression Wave Properties 2. Amplitude s The amount of displacement from the rest position s A measure of the wave e n e r g y...
