A sound source \( A \) and a reflecting surface \( B \) move directly toward each other. Relative to the air, the speed of source \( A \) is \( 20.0 \mathrm{~m} / \mathrm{s} \), the speed of surface \( B \) is \( 80.0 \mathrm{~m} / \mathrm{s} \), and the speed of sound is \( 329 \mathrm{~m} / \mathrm{s} \). The source emits waves at frequency \( 2000 \mathrm{~Hz} \) as measured in the source frame. In the reflector frame, what are the (a) frequency and (b) wavelength of the arriving sound waves? In the source frame, what are the (c) frequency and (d) wavelength of the sound waves reflected back to the source?
