What is the wave length in meters of an FM radio wave with frequency 102.5 MHz ? |
|
Answer» SOLUTION :Given frequency `V=102.5MHz` `=102.5xx10^(6)Hz=102.5xx10^(6)s^(-1)` `"Velocity of light, c "= 3 xx 10^(8) ms^(-1)` `therefore lambda=(c )/(v )=(3XX10^(8)ms^(-1))/(102.5xx10^(6)s^(-1))=2.93m` `"The wave length is 2.93 m "` |
