E Region শব্দের বাংলা অর্থ: ই অঞ্চল
E Region Meaning In Bengali ই অঞ্চল
E Region
Definition
1) In atmospheric science, the E region refers to a region of the ionosphere located at an altitude of about 90 to 120 kilometers (56 to 75 miles) above the Earth's surface. It is characterized by a high concentration of free electrons, which play a key role in the reflection and absorption of radio waves in the atmosphere.
2) In telecommunications, the E region can refer to a specific frequency range within the electromagnetic spectrum, typically around 4 to 8 megahertz. This frequency range is often used for long-distance radio communications, especially during the daytime when signals can be refracted by the E region of the ionosphere.
3) In geophysics, the E region can also refer to a layer within the Earth's mantle that lies between the upper and lower mantle. This region is characterized by its unique physical and chemical properties, and plays a crucial role in the convection and circulation of the Earth's interior heat.
Examples
