For air$-$to$-$air communications, pilots will use a frequency called "fingers" $=123\mathrm{.}45$MHz$.$ If

a pilot sends a message to another pilot $25$ miles $(1$ mile $=1609$m $)$ straight ahead $($call

straight ahead the x$-$axis$)$ with a magnetic antenna that creates the magnetic field in the y $-$

direction with a strength of $4\mathrm{.}55$ xx$10^(-10)$T :

a$.$ What direction is the electric field?

b$.$ What is the strength of the electric field?

c$.$ What is the wavelength of these radio waves?

d$.$ How much time does it take for these radio waves to travel between planes?
