1. Research the work and contributions of Canadian physicist and engineer Reginald Fessenden, one of the pioneers in the field of radio. a) What were Fessenden's notable contributions to radio and the use of radio for long-distance communication? b) Discuss how Fessenden's work involved using the wave model for light. c) Connect his work in radio to modern cellphone technology. d) Sometimes, your car radio loses reception as you drive around mountains or over long distances where the curvature of Earth becomes a factor. Generally, FM waves are lost more readily the AM waves. Explain the reasons. e) A traditional radio receiver picks up pops and whistle sounds. These sounds result from lightning in storms. Explain how this happen. f) Research how radio transmitters work. Describe how a vibrating electric dipole produces electromagnetic radiation? Explain why antennas are different lengths.Explain why a horizontal antenna would give poorer reception. g) State the differences between a sound wave and a radio wave, and explain how information from the radio station reaches the listener's ear
