Question

In 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

1.364 m

Step-by-step explanation:

We are given that

Frequency,
`\\u=110.0 MHz=110* 10^6 Hz`

`1 MHz=10^6Hz`

Speed of light,
`c=3* 10^8 m/s`

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

Wavelength,
`\lambda=(c)/(\\u)`

Using the formula

`\lambda=(3* 10^8)/(110* 10^6)`

`\lambda=2.727 m`

The distance between the nodal planes of the magnetic field=
`(\lambda)/(2)`

The distance between the nodal planes of the magnetic field=
`(2.727)/(2)=1.364 m`
