A radio station transmit radio waves with a frequency of 1,150 khz. Waht is the wavelengths of the radio waves?
To determine the wavelength of radio waves, you can use the formula:
Wavelength = Speed of Light / Frequency
The speed of light in a vacuum is commonly represented by "c" and is approximately 3 x 10^8 meters per second (m/s).
First, convert the frequency from kilohertz (kHz) to hertz (Hz) by multiplying it by 1000:
Frequency = 1,150 kHz * 1000 = 1,150,000 Hz
Now, you can substitute the values into the formula:
Wavelength = (3 x 10^8 m/s) / (1,150,000 Hz)
Calculating this gives you:
Wavelength = 260 meters
So, the wavelength of the radio waves transmitted by the radio station is approximately 260 meters.
c = freq x wavelength
c = 3E8 m/s
freq in Hz
wavelength in meters
