Can visible light produce interference fringes? Explain. Define internal energy? Prove that W = PΔV. In Newton’s ring, why are the fringes circular? Write any three/four postulates of the kinetic theory of gases? Define Least Distance of Distinct vision. How is it affected with increase of age? If a person was looking through a telescope at the full moon, how would the appearance of the moon be changed by covering half of the objective lens? Given an example of a process in which no heat is transferred to or from the system but the temperature of the system changes.
Understand the Problem
The question includes multiple sub-questions related to physics concepts such as interference, internal energy, Newton's rings, kinetic theory of gases, distinct vision, telescopes, and thermodynamics. It is asking for short answers to these specific queries.
Answer
Visible light produces interference fringes. Internal energy is total energy of particles. W = PΔV from thermodynamics. Newton's rings are circular due to equal thickness. Kinetic theory: particles in constant motion. Least distance increases with age. Covering lens reduces brightness.
Visible light can produce interference fringes due to overlapping of waves from different paths. Internal energy is the total energy within a system. W = PΔV is derived from the first law of thermodynamics. Newton’s rings are circular because of equal thickness of air film. Kinetic theory postulates: 1) Gases consist of tiny particles. 2) Particles are in constant motion. 3) Collisions are elastic. 4) There are no intermolecular forces. Least Distance of Distinct Vision is normally 25 cm but increases with age. Covering half the lens reduces brightness but not the image size. An example of no heat transfer with temperature change is adiabatic compression or expansion.

More Information
Newton’s rings’ circular pattern results from the symmetry of the lens. The least distance of distinct vision increases with age due to changes in flexibility of the eye lens. Adiabatic processes highlight the role of internal energy without heat exchange.
Tips
Avoid assuming that image size changes when part of an objective lens is covered; only brightness is reduced.
