## Question
|
|
|
|
```
|
|
It is common on airplane trips to be asked to
|
|
turn off devices whose operation involves the emission
|
|
or reception of electromagnetic waves, such as cell phones.
|
|
The justification given for this procedure is, among other
|
|
things, the need to eliminate sources of electromagnetic signals
|
|
that might interfere with the pilots' radio communications
|
|
with the control tower.
|
|
This interference will only occur if the waves
|
|
emitted by the cell phone and those received by the airplane's radio
|
|
|
|
a) are both audible.
|
|
b) have the same power.
|
|
c) have the same frequency.
|
|
d) have the same intensity.
|
|
e) propagate at different speeds.
|

Solution:
|
|
|
|
If the aircraft's communication equipment
|
|
operates on the same frequency as cell phones,
|
|
the phenomenon of interference between the
|
|
radio frequencies used by these devices can occur.
|
|
|
|
Answer: **C**

## Canarim-7B-VestibulAide Solution
|
|
|
|
```
|
|
For electromagnetic interference to occur in the airplane,
|
|
there must be two electromagnetic waves with similar vibrations,
|
|
but not identical, that is, there must be two waves with close frequencies.
|
|
|
|
Correct Answer: **C**
