How many main frontiers of fundamental science ?
Correct answer: C. 3
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
Fundamental science is commonly divided into three broad frontiers: the very small, the very large, and the very complex. These correspond broadly to studies of particles, the universe, and complex systems. Students may choose two by counting only the microscopic and cosmic frontiers and overlooking the frontier of complexity.

About Quantum Theory and Radiation
Quantum theory treats electromagnetic radiation as packets of energy called photons, with energy proportional to frequency through E equals hf. The topic covers Planck's hypothesis, photon momentum, the photoelectric effect, threshold frequency, work function and wave particle duality, distinguishing quantised energy exchange from classical continuous radiation.
