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
Giving off is emitting it and reflecting light is reflecting it
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
- light reflected from a window- light reflected from a mirror- light reflected from snow
The bouncing of light is the reflecting.
When an object is radiating light, it means that the object produces light. When an object is reflecting light, it means that light "bounces off" the surface of that object.
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
The reflecting telescope deals with light. It uses mirrors to gather and focus incoming light from distant celestial objects for observation. Sound waves are not used in reflecting telescopes.
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.

how can you tell if an object is reflecting blue light from a star
