An electromagnetic radio wave is received by a transmitter before it is converted to a sound wave. the radio wave has a wavelength of 23,076 m and a frequency of 13,000 hz. what velocity is the wave traveling at before the transmitter converts it to a sound wave? a 1.76 m/s b 0.56 m/s c 3.31 × 102 m/s d 3.00 × 108 m/s

By definition, the wavelength of an electromagnetic wave is calculated using the following formula:

Where:

\lambda = wavelength

c = speed of light =

f = frequency of the wave.

This relation means that the division of the wavelength λ between the frequency f is always equal to the speed of light.

Thus:

the velocity v of this wave must be equal to c.

Finally the correct answer is D.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
