OPTICS

                             The subject of  Optics  has been divided into  Two branches namely ray optics and Wave optics. Ray optics deals  with  the  information  of images  in  mirrors  and  lenses,  the  aberrations  of  optical  images  and  the  working  and  designing of optical  instruments.  Ray  optics is based on the  laws  of   rectilinear   propagation, reflection and refraction  of  light and the knowledge of geometry of straight lines.

                          During the first decade of the 19th Century, some more facts about light were discovered. In 1801, Thomas Yound demonstrated   interference  between  two beams  of  light,  in 1808, Malus discovered that the light reflected  from a glass was Polarized.   Grimaldi   in  1665  had  already  discovered   diffraction  of  light.   These  aspects  of  the  behaviour  of  light  i.e., Interference,  diffraction  and  Polarization are explained with  the 3-d  models, painting and selef Explanatory charts and also provided to Make your self Kits for some applications also.

                         The  straight-line path of  light when  it travels from one point to another is called a ray of light.  Rayoptics, therefore,  used  the  geometry  of  stright lines to discuss  the  reflection  of  light  from spherical mirrors and  refraction  of  light through Prisms and spherical surfaces such as lenses.  These  simple  devices from  important  components  of  optical  instruments  such as cameras, telescopes and mircroscopes.

ELECTRO MAGNETISM

                                      The  Science  of   electricity  evolved  from  the  observation  of  the  Greek Philosopher,  Thales,  in the Sixth Century BC,  that a rubbed piece of amber will attract pieces of straw.  The  Science of magnetism goes back to the observation  that  naturally  occurring   "stones"   will  attract  iron.   The   two  sciences  developmed   independently   until  1820,  when  Hans Christian  Oersted  discovered  the   connection  between  them.  He  showed  that  a  curent in a wire  can  also  produce magnetic efects, namely, that it can change the orientation of compass needle. This gave birth of a new Science, electromagnetism, which was further  developed  by many  workers;  the  most  notable  contribution  coming from  Michael Faraday   and James Clerk Maxwell. Oersted's experiment such as compass needle. Faraday argued that from Newton's thrid law, the  reverse  should also be true, i.e.,  the  magnet should also expert an equal and  opposite  force  on the  wire carrying current.   It  was  Maxwell  who  put  the  laws  of  electro-magnetism in the form a set of simple equations, called Maxwell's equations that describe the behaviour of the electric and magnetic fields.

SEMI CONDUCTOR PHYSICS

                          Materials having a small band gap between the valence and conduction bands are behave as Semiconductors. Semiconductors have a wide range of practical applications as diodes,  transistors, etc.,  and  in  a  number  of semiconductor devices.  The fabrication of digital computers is the mostly rapidly developing area of electronics.  The basic function is these  computers are performed by a combination of circuits involving semiconductor devices.

PLANETARY PHYSICS

                      The  branch  of  Science  that deals with the Study of te Universe called as Astronomy and also called as Planet Physics.  Astronomy is an observational Science.  The devices that an astronomer user for this study include otical telescopes, radio telescopes,  spacetrographs,  photographic plates, space probes etc.   This Science  deals  with the Origin, structure and evoluation of the Universe is called Cosmology. The measurement of the red shift of spectral lines suggest that the universe is expanding.  Three  theories  have  been  proposed to account for the origin and evolution of the Universe. They  are big band theory, the   steady  state  theory and pulsating theory. The red shift observed for quasars and the other observations tend to favour the bing bang theory.
