1. What is physics? (K):
   • Physics is the branch of science that deals with the study of matter, energy, and the fundamental forces that govern the behavior of the universe.
2. What is Astrophysics? (K):
   • Astrophysics is a branch of astronomy that employs the principles of physics and chemistry to understand how stars, planets, galaxies, and other celestial bodies behave.
3. Who gave the wave theory of light? (K):
   • The wave theory of light was proposed by Christian Huygens and later supported by Thomas Young.
4. Who discovered neutrons? (K):
   • Neutrons were discovered by Sir James Chadwick in 1932.
5. Who gave the theory of relativity? (K):
   • The theory of relativity was formulated by Albert Einstein. There are two versions: the special theory of relativity (1905) and the general theory of relativity (1915).
6. Name the discovery made by Sir C.V. Raman. (K):
   • Sir C.V. Raman discovered the Raman Effect, which involves the inelastic scattering of light, confirming the quantum nature of light.
7. Name the discovery made by Maxwell. (K):
   • James Clerk Maxwell formulated the set of equations known as Maxwell’s equations, which describe the behavior of electric and magnetic fields and predict the existence of electromagnetic waves.
8. Name the principle behind the airplane concept. (A):
   • The principle behind the airplane concept is Bernoulli’s Principle, which explains the relationship between air pressure and the speed of air movement.
9. Name the principle behind rocket propulsion. (A):
   • The principle behind rocket propulsion is Newton’s Third Law of Motion, stating that for every action, there is an equal and opposite reaction.
10. Who discovered X-rays? (K):
    • Wilhelm Conrad Roentgen is credited with the discovery of X-rays in 1895.
11. Who is the father of the unification field theory? (K):
    • Albert Einstein is often considered the father of the unification field theory, although he did not fully succeed in developing one.
12. What do you mean by the scientific method? (K):
    • The scientific method is a systematic approach to empirical investigation that involves making observations, forming hypotheses, conducting experiments, and drawing conclusions to acquire knowledge and understanding of the natural world.
13. Who gave the quantum theory? (K):
    • Quantum theory was developed by multiple scientists, including Max Planck, Albert Einstein, Niels Bohr, and others, to describe the behavior of particles at the quantum level.
14. Who gave the theory of the expansion of the universe? (K):
    • Georges Lemaître proposed the theory of the expansion of the universe, often associated with the Big Bang theory.
15. What is technology? (K):
    • Technology refers to the application of scientific knowledge for practical purposes, often involving the development and use of tools, machines, systems, and processes.
16. Which is the strongest force in nature? (K):
    • The strong nuclear force is the strongest force in nature, responsible for holding protons and neutrons together within an atomic nucleus.
17. Which is the weakest force in nature? (K):
    • Gravity is the weakest force in nature among the four fundamental forces.
18. What is the range of gravitational force? (K):
    • The range of gravitational force is theoretically infinite; however, its strength diminishes with distance according to the inverse square law.
19. What is the meaning of the word ‘fusis’? (K):
    • ‘Fusis’ is a Greek word meaning nature. It is related to the term “physics,” which is derived from the Greek word “physis,” meaning nature.
