a. At $20^{\circ} \mathrm{C},$ what is the frequency of a sound wave in air with a wavelength of $20 \mathrm{cm} ?$ b. What is the frequency of an electromagnetic wave with a wavelength of $20 \mathrm{cm} ?$ c. What would be the wavelength of a sound wave in water with the same frequency as the electromagnetic wave of part b?
The speed of sound in dry air at $20^{\circ} \mathrm{C}$ is 343 $\mathrm{m} / \mathrm{s}$ and the lowest frequency sound wave that the human ear can detect is approximately 20 $\mathrm{Hz}$ (a) What is the wavelength of such a sound wave? (b) What would be the frequency of electromagnetic radiation with the same wavelength? (c) What type of electromagnetic radiation would that correspond to? [Section 6.1]
