Introduction to Physical Science. 4-credit conceptually-oriented course with some algebra and with integrated laboratory component.. The course focuses on physics concepts.. Serves primarily . Speech-language Pathology Majors . Raytracing. Lecture 7: Optics. UCSD Physics 122. 2. Reflection. We describe the path of light as straight-line rays. “geometrical optics” approach. Reflection off a flat surface follows a simple rule:. Transistors, Cable Impedance. diode bridge. Lecture 8: Electronics. UCSD Physics 122. 2. Basic Circuit Analysis. What we won’t do:. common electronics-class things: RLC, filters, detailed analysis. Analog Handling. Once the microcontroller is managed, it’s often the analog end that rears its head. getting adequate current/drive. signal conditioning. noise/glitch avoidance. debounce. is one example.
