Some radiation, such as … WebFrequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour. Usually frequency is measured in the hertz unit, named in honor of the 19th-century
WebJun 6, 2024 · Since the atmosphere decreases in density as you go up in altitude it acts to refract radio waves. This has the same root cause as light bending when in passes between mediums with different refractive indices (e.g. a prism or the bending of light as look down into a swimming pool).
