Wave at interfaces (energy and power of waves). Students should be able to: ✓ distinguish between transverse and longitudinal waves. ✓ describe the superposition principle of waves, interference, diffraction, dispersion and polarization of waves. ✓ discuss wave at interfaces. ✓ describe energy and power of waves, and solve some problems. 4 The wave equation. 2 - D and 3-D wave equations. Phase and group velocities. Students should be able to: ✓ identify and apply the wave equations. ✓ describe 2 - D and 3-D wave equations, and solve some problems.
