What is the wavelength of a radio photon from an "AM" radio station that broadcasts at 740 kilohertz?
To calculate the wavelength of a radio photon, we can use the formula:
Wavelength = Speed of light / Frequency
The speed of light (c) is approximately 3.00 x 10^8 meters per second.
First, let's convert the frequency from kilohertz (kHz) to hertz (Hz):
740 kilohertz = 740,000 hertz
Now we can substitute the values into the formula:
Wavelength = (3.00 x 10^8 m/s) / (740,000 Hz)
Calculating this will give us the wavelength of the radio photon.
To calculate the wavelength of a radio photon, you can use the equation:
wavelength = speed of light / frequency
First, let's convert the frequency from kilohertz (kHz) to hertz (Hz):
740 kilohertz = 740,000 hertz
The speed of light is approximately 3.0 × 10^8 meters per second (m/s).
Now we can calculate the wavelength:
wavelength = (3.0 × 10^8 m/s) / (740,000 Hz)
Simplifying the equation gives:
wavelength = 405.41 meters (rounded to two decimal places)
Therefore, the wavelength of a radio photon from an "AM" radio station that broadcasts at 740 kilohertz is approximately 405.41 meters.
