Question

How many wavelengths of the radio waves are there between the transmitter and radio receiver if the woman is listening to an AM radio station broadcasting at 1180 kHz

Answer 1

254 m

Step-by-step 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
