Pick an option to check your answer.
Answer & Solution
Correct Answer
(B) \((A)-(III), (B)-(II), (C)-(IV), (D)-(I)\)
Step-by-step Solution
Detailed explanation
Infrared is the least energetic thus having biggest wavelength \((\lambda)\) and gamma rays are most energetic thus having smallest wavelength.
