Lon Capa HW 3 - Chem 102 fully solved 2023In order to effectively radiate a radio signal, an antenna must be at least one-half the wavelength of transmission in length, i.e., minimum antenna height = 1/2(λ). WDWS operates at a frequency of 1400. kHz. What is the minimum height (m) of the antenna that WDWS (news/talk radio) must have? The speed of light, c, is 2.998 x 10⁸ m/s. - correct answer 107.1 m An electron is excited from the ground state to n=5 in a hydrogen atom. Decide if the foll...
