Short answer questions on Solid state physics

In summary, solid state physics is a branch of physics that studies the physical properties of solid materials at the atomic and molecular level. It uses principles such as quantum mechanics, statistical mechanics, and electromagnetism to understand the behavior of solids and predict their properties. Solid state physics has connections to other fields of physics and has a wide range of real-world applications in areas such as electronics, energy storage, and medical devices.

1. Platinum is silver and shiny because of its unique electronic structure. It has a high number of valence electrons, which are loosely bound and can easily move around, making it a good conductor of electricity. This also allows for the reflection of light, giving it a shiny appearance.

2. The color of aluminum oxide can vary due to the presence of impurities or defects in its crystal structure. When pure, it is transparent because its atoms are arranged in a regular pattern that allows light to pass through undisturbed. However, when impurities or defects are present, they can absorb certain wavelengths of light, resulting in the material appearing red or blue.

3. Quartz is transparent because it is composed of a repeating pattern of silica tetrahedra. These tetrahedra are arranged in a way that allows light to pass through without being scattered or absorbed. This regular and uniform arrangement of atoms gives quartz its transparency.
