- The importance of the optical phenomenon (i.e., Its Engineering applications include interference, diffraction, and polarization.
- Understanding lasers’ emission mechanisms and utility for coherent light sources for low- and high-energy applications. Study of propagation through optical fibers and implications for visual communications.
- New utility avenues are now available for magnetic and dielectric materials that could be used to make micro-devices.
- It is essential to be familiar with theoretical and practical acoustics for engineering acoustics. Explain the importance of ultrasound and how it is used in NDT applications.
- Using Bragg’s law, learn about the periodic arrangement of atoms within Crystalline solids.
