Q117 (IAS/1998) Science & Technology › Basic Science (Physics, Chemistry, Biology) › Atomic and nuclear physics Answer Verified

Match the names of outstanding Indian scientists given in List I with area of their specialised work given in List II and select the correct answer using the codes given below the lists

List I | List II
I. Dr. Raja Ramanna | (A) Plant Chemistry
II. Dr. M.S. Swaminathan | (B) Nuclear Physics
III. Prof. U.R. Rao | (C) Thermodynamics and astrophysics
IV. Prof. Meghnad Saha | (D) Space research
| (E) Agricultural sciences

Result
Your answer: —  Â·  Correct: C
Explanation

The correct answer is Option 3 (I-B, II-E, III-D, IV-C) because it accurately aligns each scientist with their pioneering contributions to Indian science:

  • Dr. Raja Ramanna (I-B): A towering figure in Nuclear Physics, he played a crucial role in India's nuclear program and directed the first nuclear device test (Smiling Buddha) in 1974.
  • Dr. M.S. Swaminathan (II-E): Known as the "Father of the Green Revolution in India," his work in Agricultural Sciences transformed India from a food-deficient nation to a self-sufficient one.
  • Prof. U.R. Rao (III-D): An eminent space scientist who served as the Chairman of ISRO, he led India's efforts in Space Research and the development of satellite technology like Aryabhata.
  • Prof. Meghnad Saha (IV-C): Famous for the "Saha Ionization Equation," his fundamental work in Thermodynamics and Astrophysics revolutionized the understanding of stellar atmospheres.

Other options are incorrect as they misattribute these distinct specializations; for instance, Dr. Swaminathan is exclusively linked to agriculture (E), not plant chemistry (A) or nuclear physics (B).
