What is the Importance of solid state physics in daily life?

Answer 1

Solid state physics is a study of solid (rigid matter). Solid state physics applies everywhere around us. It involves how the macro-scale properties of solid materials result from their micro-scale properties. Most of the solids are arranged in such a way that their atoms are in an orderly repetitive arrays so the solids we see around are the examples of solid state physics e.g. sugar molecules, salt (Nacl), glass etc. So, it forms the theoretical basis of material science. Its applications are in the technology of transistors and semiconductors. Quantum mechanics, Metallurgy, electromagnetism, crystallography, etc are all part and parcel of solid state physics.

Answer 2

In this digital world, theories of solid-state physics apply to almost all objects in our surroundings. It discusses how the macro-scale properties resulted from the micro-scale properties of solids. It also studies how the atomic properties affect the overall properties of the solid.

It forms the theoretical base for material science and has various applications in practical life, as discussed above.

Solid-state physics studies the characteristics of atoms and their thermal, electrical, magnetic, and mechanical properties and their interdependence, which further suggests the use of different kinds of atoms per their applications. For example, the regular and irregular patterns of crystalline metals and non-metals help design window glass.
