Question

Many of todays cell phones operate at a frequency at either 1900 or 800 MHz (MHz is megahertz, or 100 Hz). The higher freque

Answer 1

Answer #1

frequency, v= 1900 MHz = 1900x106 gol = 19x108 gt Frequency , = (= speed of light a= wavelength 3x108 mst 198108 8A = Oilom.

Learning Goal: To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol A (lowercase Greek "lambda"), is usually measured in meters. Every wave also has a frequency, which is the number of wavelengths that pass a certain point during a given period of time. Frequency, given...
