About This Book

The lectures present a practical, experiment-focused introduction to wave phenomena across media, beginning with surface waves and ripples on liquids and the principles of wave motion, wavelength, velocity, reflection, refraction, and interference. They then examine waves generated by moving bodies and ship-wave resistance, illustrating fluid flow, vortices, and model testing. Subsequent chapters treat sound as longitudinal air waves, its production, propagation, hearing range, and devices like sirens and the phonograph. Throughout, visible demonstrations and mathematical rules are used to connect water and air waves to more abstract electromagnetic waves in the proposed æther, emphasizing comparative physical principles and experimental methods.

About the Author

Sir J. A. Fleming

Sir J. A. Fleming was a prominent engineer and physicist known for his significant contributions to the field of wireless communication. He is best remembered for his work on Hertzian wave wireless telegraphy, which laid the groundwork for modern radio technology. His notable publications include "Hertzian Wave Wireless Telegraphy" and "Waves and Ripples in Water, Air, and Æther," where he explored the principles of wave propagation in various media. Fleming's research not only advanced scientific understanding but also had a lasting impact on telecommunications, making him a key figure in the development of early 20th-century technology.
