An FM radio station broadcasts at a frequency of 107.9 Hz. What is the wavelength of the radio signal?
c = fw
speed of light = frequency x wavewlength
You know c is 3E8 m/s. You're given frequency in Hz. Substitute and solve for wavelength in meters. Post your work if you need help.
To calculate the wavelength of a radio signal, you can use the formula:
λ = c / f
Where:
λ = wavelength (in meters)
c = speed of light (approximately 3 x 10^8 meters per second)
f = frequency (in hertz)
In this case, the frequency is 107.9 Hz. Plugging it into the formula, we get:
λ = (3 x 10^8 m/s) / 107.9 Hz
Calculating this, we find:
λ ≈ 2.78 meters
Therefore, the wavelength of the radio signal is approximately 2.78 meters.
To find the wavelength of a radio signal, you can use the formula:
wavelength = speed of light / frequency
where the speed of light is approximately 3.00 x 10^8 meters per second.
In this case, the frequency of the FM radio station is given as 107.9 Hz.
Let's plug the values into the formula to find the wavelength:
wavelength = (3.00 x 10^8 m/s) / (107.9 Hz)
To calculate this, we divide the speed of light by the frequency:
wavelength = 2.78 x 10^6 meters
Therefore, the wavelength of the radio signal from the FM station is approximately 2.78 x 10^6 meters.
