Question

Quizplus · Accepted Answer

The wavelength of a radio wave is given by the formula:λ = c/fwhere:λ is the wavelength in metersc is the speed of light in meters per secondf is the frequency in hertzIn this problem, we are given that the frequency of the radio wave is 10.4 MHz, which is equal to 10.4 × 10^6 Hz. The speed of light is 3.00 × 10^8 m/s. Substituting these values into the formula, we get:λ = 3.00 × 10^8 m/s / 10.4 × 10^6 Hz= 28.8 mTherefore, the wavelength of the radio wave is 28.8 m.
