    intense chorus waves propagating away from the equator. Both waves are at the same frequency. Using the wave nor-mal directions of these waves, a ray tracing study shows that the waves observed by SC1, SC2, and SC4 cross the equato-rial plane at the same location as the waves observed by SC3. SC3 which is 30 minutes late observes the waves that. ionospheric sounding by radio signals is based on the existence of the phenomenon of dispersion of radio waves in the microwave range electron plasma forming the Earth's ionosphere. Refractive index of radio signal while passing through the atmosphere from a transmitter located on the emitting satellite is determined by the formula.

      Additionally, sometimes a person ingests or is injected with an opaque X-ray fluid that will fill a space of interest for X-ray imaging. A computerized tomography (CT) scan is usually a series of X-rays taken from different angles and then assembled into a three-dimensional model by a computer. Tomography means a picture of a slice.

Introduction [2] When a radio antenna transmits HF waves, part of the energy enters the ionosphere, where the waves refract, penetrating the ionosphere or returning back to the ground depending on the frequency, the ionospheric condition, and the elevation angle.
