Question:
Power of a thick lens is smaller than the thin lens. (T/F)
Power of a thick lens is smaller than the thin lens. (T/F)
Show Hint
The power of a lens is inversely proportional to its focal length. A thicker lens has a longer focal length, leading to a smaller power.

Solution and Explanation
Step 1: Understanding the concept.
The power of a lens is inversely related to its focal length. A thick lens has a slightly longer focal length compared to a thin lens of the same curvature, and therefore, its power is lower than that of the thin lens.
Step 2: Analyzing the statement.
The statement is True, as the power of a thick lens is indeed smaller than the power of a thin lens, due to the difference in focal lengths.
Step 3: Conclusion.
The correct answer is True, as the power of a thick lens is smaller than that of a thin lens.

Ferromagnetic substances are those which get strongly magnetized when placed in an external magnetic field. They have strong tendency to move from a region of weak magnetic field to strong magnetic field, that is, they get strongly attracted to a magnet. The individual atoms (or ions or molecules) in a ferromagnetic material possess a dipole moment as in a paramagnetic material. However, they interact with one another in such a way that these spontaneously align themselves in a common direction over a macroscopic volume called domain. Each domain has a net magnetization. Typical domain size is 1 mm and the domain contains about \(10^{11}\) atoms. In the first instant the magnetization varies randomly from domain to domain and there is no bulk magnetization. When we apply an external magnetic field \(B_0\) the domains orient themselves in the direction of \(B_0\) and simultaneously that domain oriented in the direction of \(B_0\) grows in size. We may wonder as to what happens when the external field is removed, in some ferromagnetic materials the magnetization persists. Such materials are called hard magnetic materials of hard magnets. Alnico, an alloy of iron, aluminium, nickel, cobalt and copper is one such material. There is a class of magnetic materials in which the magnetization disappears on removal of the external field. Soft iron is one such material. Such materials are called soft ferromagnetic materials. There are number of elements which are ferromagnetic. Iron, cobalt, Nickel, gadolinium etc. The ferromagnetic property depends on temperature. At high enough temperature a ferromagnet becomes a paramagnet. That domain structure disintegrates with temperature. This disappearance of magnetization with the temperature is gradual.- PSEB XII - 2025
