Question

a certain experiment, a radio transmitter emits sinusoidal electromagnetic waves of frequency 110.0 MHz in opposite directions inside a narrow cavity with reflectors at both ends, causing a standing-wave pattern to occur. (a) How far apart are the nodal planes of the magnetic field

    Answer:

    1.364 m

    Explanation:

    We are given that

    Frequency,f=110 MHz=110\times 10^{6}Hz

    1MHz=10^6Hz

    We have to find the distance between the nodal planes of the magnetic field.

    We know that

    Wavelength,\lambda=\frac{c}{f}

    Where c=3\times 10^8m/s

    Using the formula

    \lambda=\frac{3\times 10^8}{110\times 10^6}=2.727 m

    Distance between nodal planes of the magnetic field

    d=\frac{\lambda}{2}

    d=\frac{2.727}{2}=1.364 m
