Dense Index:
An index record appears for every search key value in file.
This record contains search key value and a pointer to the actual record.
Sparse Index:
Index records are created only for some of the records.
To locate a record, we find the index record with the largest search key value less than or equal to the search key value we are looking for.
We start at that record pointed to by the index record, and proceed along the pointers in the file (that is, sequentially) until we find the desired record.

Why the refractive index of ice is lower than that of water?
The refractive index of a material is related to how light propagates through it. Ice has a lower refractive index than water because its molecular structure is less dense and more sparse compared to water. This difference in molecular arrangement affects how light interacts with the substance, leading to a lower refractive index in ice compared to water.
