Answer:
Less than 100 picometers (pm), or 4 x 10^9 inches.
Step-by-step explanation:
Gamma-rays fall in the range of the EM spectrum above soft X-rays. Gamma-rays have frequencies greater than about 1,018 cycles per second, or hertz (Hz), and wavelengths of less than 100 picometers (pm), or 4 x 10^9 inches.
