A radio signal has a frequency of 103.1 MHz,calculate the wavelength
wavelength=speedlight/freq
To calculate the wavelength of a radio signal, you can use the following formula:
Wavelength = Speed of Light / Frequency
The speed of light is a constant value and is approximately 3 x 10^8 meters per second. The frequency given is 103.1 MHz, which means it is in units of megahertz.
First, convert the frequency from megahertz (MHz) to hertz (Hz):
103.1 MHz = 103.1 x 10^6 Hz
Next, plug the values into the formula:
Wavelength = (3 x 10^8 m/s) / (103.1 x 10^6 Hz)
Simplifying the formula:
Wavelength = 2.905 x 10^3 m
Therefore, the wavelength of the radio signal is approximately 2.905 kilometers.
To calculate the wavelength of a radio signal, you can use the following formula:
Wavelength (λ) = Speed of Light (c) / Frequency (f)
The speed of light (c) is approximately 3 x 10^8 meters per second (m/s).
In this case, the frequency (f) is given as 103.1 MHz, which means 103.1 million cycles per second. To convert it to Hz, we need to multiply it by 10^6.
So, we have:
Frequency (f) = 103.1 MHz = 103.1 x 10^6 Hz
Now, we can substitute the values into the formula:
Wavelength (λ) = (3 x 10^8 m/s) / (103.1 x 10^6 Hz)
Simplifying the equation:
Wavelength (λ) = 2.908 x 10^2 meters
Therefore, the wavelength of the radio signal with a frequency of 103.1 MHz is approximately 290.8 meters.
