Question
a. An FM radio station broadcasts at a frequency of101.3 MHz. What is the wavelength?b. What is the frequency of a sound source that producesthe same wavelength in 20°C air?
Step 1
3 MHz. We need to convert this frequency to Hz by multiplying by $10^6$ because 1 MHz = $10^6$ Hz. So, the frequency $f$ is $101.3 \times 10^6$ Hz. Show more…
