Explain about the term holography.
Holography
Holography (through the Greek hòlòs entire + grafè writing, drawing) is a technique which permits the light scattered by an object to be recorded and later reconstructed than it appears as when the object is in similar position relative to the recording medium as this was when recorded. The image changes like the position and orientation of the viewing system changes within exactly similar way as when the object were still present, therefore making the recorded image (hologram) shows three dimensional. There holograms can also be made by using other kinds of waves.
The method of holography can also be used to optically store, process and retrieve information. When holography is commonly used to exhibit static 3-D pictures, this is not yet possible to produce arbitrary scenes by a holographic volumetric display.
Explain about the Homojunction Laser in brief. Homojunction Laser: Assume that GaAs be doped with T providing n-type material and with Ge providing p-type material. In forwa
Poisson spot (S.D. Poisson) Originally Poisson predicted the existence of such spot, and utilized the prediction to revel how the wave theory of light have to be in error to g
For silicon the forbidden gap is (A) 1.1ev. (B) 0.25ev. (C) 0.5ev. (D) 0.7ev. Ans: For silicon the forbidden gap is 1.1ev.
Q. Give the drawbacks of Sommerfeld’s atom model? Drawbacks of Sommerfeld's atom model: (i) It couldn't explain the distribution and arrangement of electrons in atoms.
What are slide emitting fibers? No, there are not any side-emitting fibers. All fiber optics acquires the light at one end and transport this to the other. While light enters a
How is plastic clad silica fibre used in optical fibres? Plastic clad silica fibre: Plastic clad silica fibre (PCS) is other type of optical cable. This has an attenuation l
A quarter of a wavelength is equal to how many degrees of phase? A quarter of wavelength is equaivalent to 90 degrees of phase.
When a P-type semiconductor is suitably joined to an N-type semiconductor, then resulting arrangement is called P-N junction or P-N junction diode Depletion region : On account
