AM and FM radio waves are transverse waves that consist of electric and magnetic disturbances. These waves travel at a speed of `3. 00 xx 10^(8)` m/s.
A station broadcasts an AM radio wave whose frequency is `1230 xx 10^(3)` Hz (1230 kHz on the dial) and an FM radio wave whose frequency is `91.9 xx 10^6` Hz (91.9 MHz on the dial). Find the distance between adjacent crests in each wave.

Explanation

To find the distance between adjacent crests (wavelength) of the AM and FM radio waves, we will use the formula that relates the speed of a wave (v), its frequency (ν), and its wavelength (λ):

\[ v = ν \times λ \]

From this formula, we can rearrange it to find the wavelength:

\[ λ = \frac{v}{ν} \]
