Answer & Solution
Correct Answer
(B) (C), (D), (B), (A)
Step-by-step Solution
Detailed explanation
1. Gamma rays (C): Have the highest frequency and shortest wavelength. 2. X-rays (D): Follow gamma rays in terms of energy and frequency. 3. UV rays (B): Have lower frequency than X-rays but higher than visible light and radio waves. 4. FM radio waves (A): Have the lowest…
