Host Dr. J.N. Shive's presence as a lecturer is excellent - it's understandable by a layperson even when he branches into equations, because he uses copious amounts of real-world examples to bolster the material. • • Shive's role at Bell Labs was more than just a great lecturer: he worked on early transistor technology, inventing the phototransistor in 1950, and the machine he uses in the film is his invention, now called the Shive Wave Machine in college classrooms. • • Dr. J.N. Shive of Bell Labs demonstrates and discusses the following aspects of wave behavior: • • Reflection of waves from free and clamped ends • Superposition • Standing waves and resonance • Energy loss by impedance mismatching • Reduction of energy loss by quarter-wave and tapered-section transformers • Original audience: college students • • Produced at Bell Labs • • Footage courtesy of AT T Archives and History Center, Warren, NJ
