Answer:

254 m

Explanation:

Applying,

v = λf............... Equation 1

Where v = velocity of radio wave, λ = wave length, f = frequency

make λ the subject of the equation

λ = v/f............ Equation 2

From the question,

Given: f = 1180 kHz = 1180000 Hz

Constant: v = 3×10⁸ m/s

Substitite into equation 2

λ  = 3×10⁸/1180000

λ  = 2.54×10²

λ  = 254 m
