Topic 1: Electromagnetic Waves
Electromagnetic waves differ from mechanical waves in thatthey do not require a medium to propagate. This means thatelectromagnetic waves can travel not only through air and solidmaterials, but also through the vacuum of space.
According to your Knowledge, answer the followingquestions:
- Describe the characteristic of Electromagnetic Waves?
- Radio Waves travel along different paths:
a. State their names?
b. Which of them does Loran-C receiver receive?
Topic 2: Loran-C and e-Loran Systems
Two navigation systems that produce position through themeasurement of the difference in times of radio signals from two ormore synchronized transmitters at fixed points. Such systemsrequire the use of a receiver, which measures the timedifference.
According to your Knowledge, answer the following questions:(Within 600 words)
