A sound wave and a radio wave both have frequency 15 kHz. Find the ratio of the radio wavelength to the sound wavelength in air ( $v_{s} = 340$ m/s, $c = 3 \times 1 0^{8}$ m/s).

Answer:

880000.00

Solution:

$λ = v / f$ at equal frequency, so the ratio is $c / v_{s} = 3 \times 1 0^{8} /340 = 8.8 \times 1 0^{5}$ .
