The am station kbor plays your favorite music from the 20's and 30's at 1290 khz. find the wavelength of these waves.

The useful information here is the frequency expressed in 1290 kHz or 1290 per 0.001 seconds. We use the formula relating the speed of light, frequency and wavelength written below:

c = λν

where c is the speed of light (3*10⁸ m/s)

λ is the wavelength

ν is the frequency

Solving for λ,

λ = c/v = (3*10⁸ m/s) / (1290/0.001 s) = 232.56 m
