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

Respuesta :

Answer:

1.364 m

Explanation:

We are given that

Frequency,f=110 MHz=[tex]110\times 10^{6}Hz[/tex]

[tex]1MHz=10^6Hz[/tex]

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

We know that

Wavelength,[tex]\lambda=\frac{c}{f}[/tex]

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

Using the formula

[tex]\lambda=\frac{3\times 10^8}{110\times 10^6}=2.727 m[/tex]

Distance between nodal planes of the magnetic field

[tex]d=\frac{\lambda}{2}[/tex]

[tex]d=\frac{2.727}{2}=1.364 m[/tex]
