The basic principle on which optical source work is absorption, spontaneous emission and stimulated emission.

When light is incident on a semiconductor material, some photons get absorbed in the material which then transfer their energy to the electrons in the ground state and cause them to migrate to the excited …

ADD COMMENT EDIT

@Sharad Changes you need to do :

Use some text highlighting: for example - This phenomenon is called absorption
Properly write these mathematical equations: for example - correct this P=P0cosθ
Use Headers for this: Part B: LED Structure
