Frequencies of gamma rays, X-rays and ultraviolet rays are a, b and c respectively. Choose their correct order.

G1 Physics · Accepted Answer

Step 1: In the electromagnetic spectrum the frequency of gamma rays is greater than that of X-rays, and X-rays greater than ultraviolet. Step 2: Therefore for the question's symbols: a (γ-rays) > b (X-rays) > c (UV rays). Step 3: Answer A. Final answer: (A) a > b > c.
