What is the wave length in meters of an FM radio wave with frequency 102.5 MHz ?

Explanation

Given frequency v = 102.5 MHz
`=102.5 xx 10^(6) Hz = 102.5 xx 10^(6)s^(-1)`
velocity of light, `c = 3 xx 10^(8) ms^(-1)`
`:. lambda = (c)/(v) = (3 xx 10^(8) ms^(-1))/(102.5 xx 10^(6)s^(-1)) = 2.93 m`
The wave length is 2.93 m.
