A scientist is designing a device that will kill harmful cells in the human body using high-energy waves. Which type of wave would be most
effective in accomplishing this goal?
A. X-rays would be the best choice because they have a long wavelength and a low frequency.
B. Infrared waveswould be the best choice because they have a short wavelength and a high frequency.
C. Radio waves would be the best choice because they have a long wavelength and a low frequency.
D. Gamma rays would be the best choice because they have a short wavelength and a high frequency.
