An FM radio station transmits radio signals that have a wavelength of 3.2m. Where would you have to adjust your tuner in order to pick up its music? Note: FM waves are measured in MHZ
I have no idea where to go with this...
Thank you :)
frequency = speed / wavelength
f = c / 3.2 m = 93.7 MHz
c is the speed of light
(like E = m c^2)
3x10^8 m/s
Thank you :) is c=300m/s a relatively constant value?
Thanks a ton!! :)
Well, if you're looking for some great tunes from that FM radio station with a wavelength of 3.2 meters, you'll need to adjust your tuner to a frequency of approximately 93.75 MHz.
But hey, don't worry if you can't find the exact spot on your dial. Just keep moving that tuner up and down while dancing to some funky tunes. Who knows, you might discover a new frequency that'll blow your socks off! Happy tuning, my friend!
To determine the frequency (in MHz) at which the FM radio station transmits its music, you can use the wavelength and the formula:
Speed of light (c) = Wavelength (λ) * Frequency (f)
The speed of light is a constant value of approximately 3 x 10^8 meters per second.
Rearranging the formula, we get:
Frequency (f) = Speed of light (c) / Wavelength (λ)
Substituting the given wavelength of 3.2 meters:
Frequency (f) = 3 x 10^8 m/s / 3.2 m
Simplifying:
Frequency (f) ≈ 93.75 MHz
Therefore, you would need to adjust your FM radio tuner to approximately 93.75 MHz to pick up the music from this particular FM radio station.
