n In radiofrequency (RF) ablation, asmall needle is inserted into a cancerous tumor. When radiofrequency oscillating currents are sent into the needle, ions in theneighboring tissue respond by vibrating rapidly, causing localheating to temperatures as high as 100 °C. This kills the cancerous cells and, because of the small size of the needle, relatively fewof the surrounding healthy cells. A typical RF ablation treatmentuses a frequency of 750 kHz. What is the wavelength that suchradio waves would have in a vacuum?
