Account for the Some of the very old glass objects appear slightly milky instead of being transparent.

**Step-by-Step Solution:** 1. **Understanding Glass Structure**: Glass is classified as an amorphous solid, meaning it lacks a long-range ordered structure typical of crystalline solids. This amorphous nature allows glass to have unique properties, including transparency. 2. **Behavior of Amorphous Solids**: When glass is heated, it softens and can flow without transitioning into a liquid state. This characteristic is due to the disordered arrangement of particles in glass. 3. **Crystallization Process**: Over time, especially under certain conditions such as prolonged heating or changes in temperature, some amorphous solids, including glass, can undergo a process called crystallization. This means that some regions of the glass may start to form a crystalline structure. ...

Some glass objects from ancient civilisations look milky instead of being transparent. Explain.

A transpar ent rod 40 cm long is cut flat at one end and rounded to a hemispherical surface 12 cm radius at the other end. A small object is embedded within the rod along its axis and half way between its ends. When viewed from the flat end of the rod, the object appears 10 cm deep. What is its apparent depth when viewed from the curved end?

Account for the yellow colour that appears in concentrated nitric acid when left standing in ordinary glass bottle.

A ray of light is incident at an angle alpha on the boundary separating two transparant media. It transmited in other medium. If the angle incidence is increased very slightly, the ray gets reflected in the same medium. The different between angles of deviation in the two cases will close to
