This lecture from The Royal Institution's 1972 Christmas Lectures series features Geoffrey G. Gouriet demonstrating the mechanical behavior of waves in his second presentation titled "Getting rid of the wires." Begin with an exploration of how mechanical waves are produced, propagate, and interact with other waves, then discover how this behavior is analogous to electromagnetic waves. Learn various methods for producing and transmitting radio waves that can be translated into information, such as using Morse code to remotely control a lamp. Understand how Earth's atmosphere can be utilized to transmit radio waves across long distances. Part of Gouriet's six-lecture series exploring the science behind radio communications, this 59-minute presentation was recorded on December 28, 1972, and offers valuable insights into the principles of wireless communication technology.
