Answer: <u>Gamma rays (violet) have the shortest wavelengths and the highest frequencies.</u>
Explanation: The wavelength of the gamma rays is less than 0.01 nanometers. The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength.
The answer is Carbon. Beyond being the only element listed here that is located in the second row, it is also in the fourteenth column of the table if you count from left to right. Hope this helps!
