A Boston radio station broadcasts at a frequency of 93.7 MHz (M = mega; 1 MHz = 106 Hz). What is the wavelength of this EM radiation in meters?
To find the wavelength of the electromagnetic (EM) radiation, we can use the formula:
wavelength = speed of light / frequency
The speed of light is approximately 3 x 10^8 meters per second.
Given that the frequency is 93.7 MHz, which is equivalent to 93.7 x 10^6 Hz, we can substitute these values into the formula:
wavelength = (3 x 10^8 m/s) / (93.7 x 10^6 Hz)
Canceling out the 10^6 terms, we get:
wavelength = (3 x 10^8 m/s) / (93.7 Hz)
Performing the division, we find:
wavelength ≈ 3.2 meters
Therefore, the wavelength of this EM radiation is approximately 3.2 meters.
To find the wavelength of this electromagnetic (EM) radiation, we can use the equation:
Wavelength = Speed of Light / Frequency
Where the speed of light is approximately 3.00 x 10^8 meters per second (m/s).
Given that the frequency is 93.7 MHz = 93.7 x 10^6 Hz, we can plug these values into the equation:
Wavelength = (3.00 x 10^8 m/s) / (93.7 x 10^6 Hz)
Dividing the numerator by the denominator:
Wavelength ≈ 3.20 meters
Therefore, the wavelength of this EM radiation is approximately 3.20 meters.
