Optical Storage Medium
it is the rebond of light in the same medium when it meets a reflecting surface neglecting the light absorbtion
CDRW and DVDRW
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction
This type of storage is called optical storage. Data is stored by encoding information as microscopic light and dark spots on the disc surface, which can be read by a laser beam in devices such as CD-ROMs, DVDs, and Blu-ray discs.
Fermat's principle->the path of light will take after reflecting from a surface or passing through more than one medium according to the principal, light follows the path that will take the least time
Giving off is emitting it and reflecting light is reflecting it

no they do not have a medium.
c divided by the index of refraction of the medium = the speed of light in the medium.
