Question

An FM radio station broadcasts electromagnetic radiation at a frequency of 101.7 MHz. The wavelength of this radiation is ________ m.

Answer #1

We know that frequency, = c / λ

Where

c = speed of light = 3x 10^{8} m/s

= frequency = 101.7
MHz = 101.7x10^{6} Hz

λ = wave length = ?

Plug the values we get λ = c /

= (3x 10^{8} m/s) / (101.7x10^{6} )

= 2.95 m

Therefore the wavelength of this radiation is 2.95 m

Suppose a popular FM radio station broadcasts radio waves with a
frequency of 90. MHz . Calculate the wavelength of these radio
waves. Round your answer to 2 significant digits.

An AM radio station broadcasts an electromagnetic wave with a
frequency of 712 kHz, whereas an FM station broadcasts an
electromagnetic wave with a frequency of 89.1 MHz. How many AM
photons are needed to have a total energy equal to that of one FM
photon?

An AM radio station broadcasts an electromagnetic wave with a
frequency of 916 kHz, whereas an FM station broadcasts an
electromagnetic wave with a frequency of 91.8 MHz. How many AM
photons are needed to have a total energy equal to that of one FM
photon?

FM radio station KRTH in Los Angeles broadcasts on an assigned
frequency of 101 MHz with a power of 50,000 W.
(a) What is the wavelength of the radio waves produced by this
station?
(b) Estimate the average intensity of the wave at a distance of
44.4 km from the radio transmitting antenna. Assume for the purpose
of this estimate that the antenna radiates equally in all
directions, so that the intensity is constant over a hemisphere
centered on the...

Calculate the wavelength of each frequency of electromagnetic
radiation:
Part A
101.0 MHz (typical frequency for FM radio broadcasting) Express
your answer using four significant figures.
Part B
1075 kHz (typical frequency for AM radio broadcasting) (assume
four significant figures)
Part C
835.6 MHz (common frequency used for cell phone
communication)

AN FM radio station broadcasts at a frequency of 96 MHz.What
inductance should be paired with a 6.0 pF capacitor to build a
receiver circuit for this station?

What
is the wavelength used by a radio station that broadcasts at a
frequency of 920 kHz? (c = 3.00 × 108 m/s) when water has an index
refraction of 1.33

You've decided to build a radio to listen to your favourite FM
radio station, which broadcasts at 93.90 MHz. For the tuner, you'll
be using an RLC circuit, but the only inductor you happen to have
on hand has a value of 0.510 μH. Unfortunately, there's another
radio station — which you don't want to listen to — at a nearby
frequency of 93.50 MHz. To prevent any interference from this 93.50
MHz radio station, you want the peak current...

What is the wavelength used by a radio station with a
transmitting frequency of 104.5 MHz?

A radio station transmits isotropically (that is to say in all directions) electromagnetic radiation at the frequency of 98.6 MHz. At a certain distance from the radial station the intensity of the wave is I = 0.291 W / m^2.
a) What will be the intensity of the wave at a quarter of the distance from the radio station?
b) What is the wavelength of the transmitted signal?
If the antenna power is 8 MW.
c) At what distance from...
