Am radio signals use amplitude modulation of the radio waves to transmit a signal. a typical wavelength of an am radio wave is 300. meters. what is the frequency of such a radio wave? a) 1.00 âµhz b) 1.00 mhz c) 1.00 khz d) 1.00 mhz e) 1.00 hz

The frequency of such a radio wave is 1 MHz.

(d) is correct option

Explanation:

Given that,

Wave length = 300 m

We know that,

Speed of light

We calculate the frequency

Using formula of frequency

Put the value into the formula

Hence, The frequency of such a radio wave is 1 MHz.
