Question

In old monuments glass apparatus appears to be thin at top and thick at bottom. Why

Solution

Dear Student,

Glass is a supercooled liquid. It is an amorphous solid and amorphous solid has a tendency to flow, though very slowly due to high viscosity. Therefore, on passage of time, it flows downwards and hence thickening of glass can be seen at the bottom.

Q. It is stated that glass panes fixed to windows of old buildings are invariably found to be slightly thicker at bottom than at the top. In this case what's he conveying to us. Is it that the glass flows down very slowly at room temperature or at high temperature.

Q. A lean boy named Ramesh placed a glass slab of refractive index

\frac{3}{2}

on his photograph. He felt it more interesting as his face appeared bigger than the original size when observed from the top of the glass slab. He also observed that the photo appears at a height of

1.5

cm from the bottom. He then placed another glass cube made of different material and having the same thickness over the first glass cube. Now, he himself started to laugh by seeing his photograph as it appeared still bigger than the previous. When observed from the top the photograph appears to be at a height of

4

cm from the bottom. Determine the refractive index of the second glass cube.
