    Answer:

    3m

    Explanation:

    89.1 MHz means

    89.1×10^6 cycles/second.

    Electromagnetic radiation (including radio waves) travel at

    3.0×10^8meters/second

    Wavelength = Speed/Frequency

    The wavelength of a

    89.1MHz radio signal is

    3.0×10^8/89.1×10^6

    = 0.03×10^2

    = 3meters
