Question

Radio Station: What is the wavelength of a radio station photon from an AM radio station that broadcast at 1000 kilo-hertz? Remember that λ = c/f, where λ is the wavelength, f is the frequency and c is the speed of light (c = 300000 km/s)

Answer 1

Answer: The wavelength of a radio station photon from an AM radio station that broadcast at 1000 kilo-hertz is 3000 m.

Step-by-step explanation:

To calculate the wavelength of light, we use the equation:

`\lambda=(c)/(\\u)`

where,

= wavelength of the light = ?

c = speed of light = 300000 km/s =
`3* 10^8m/s` (1km=1000m)

`\\u` = frequency of light = 100kHz = 100000Hz or (1kHz=1000Hz)

`\lambda=(3* 10^8m/s)/(100000s^(-1))`

`\lambda=3000m`

Thus the wavelength of a radio station photon from an AM radio station that broadcast at 1000 kilo-hertz is 3000 m.
