Who were the scientists that the Kennelly-Heaviside layer was named after?
Q: Who were the scientists that the Kennelly-Heaviside layer was named after?
A: The Kennelly-Heaviside layer was named after Arthur Edwin Kennelly and Oliver Heaviside.
Q: Who showed the existence of the Kennelly-Heaviside layer?
A: The existence of the Kennelly-Heaviside layer was shown by Edward V. Appleton, an English physicist who received the Nobel Prize in the year 1947.
Q: What is the Kennelly-Heaviside layer?
A: The Kennelly-Heaviside layer or E region is a part of the ionosphere, which is the top part of the Earth's atmosphere that is full of electricity and magnetism, situated 90 to 150 kilometers from the Earth's surface.
Q: What type of electromagnetic radiations can the Kennelly-Heaviside layer reflect?
A: The Kennelly-Heaviside layer is capable of reflecting medium shortwave electromagnetic radiations, or the EM radiations whose frequency ranges between 300 kHz to 3MHz.
Q: When did the Kennelly-Heaviside layer become a popular means of communication?
A: The Kennelly-Heaviside layer became a popular means of communication in the late 1920s when AM signals (Amplitude Modulated) were transmitted over long distances.
Q: What advantage do AM signals have when bouncing off the Kennelly-Heaviside layer?
A: AM signals can bounce off the Kennelly-Heaviside layer, which allows them to go further than signals which cannot bounce off the layer. This means that the sender and receiver of the signal could be over the horizon from each other, and the signal can bounce off the layer in the sky in between them.
Q: What is the frequency range of EM radiations that can be reflected by the Kennelly-Heaviside layer?
A: The frequency range of EM radiations that can be reflected by the Kennelly-Heaviside layer is between 300 kHz to 3MHz.
