Suppose that the electric field part of an electromagnetic wave in vacuum is vec(E )={(3.1 N//C)cos [(1.8 rad//m)y+(5.4xx10^(6)rad//s)]}hat(i)What is the frequency v ? |

Answer» Solution :From equation (3), `omega = 5.4xx10^(6)(rad)/(s)` `therefore 2pi V=5.4xx10^(6)(rad)/(s)` `therefore v=(5.4xx10^(6))/(2xx3.14)=8.599xx10^(5)Hz` `~~86 " MHZ"`…(6) |
