Wave Optics


1. WAVEFRONT: The locus of every one of those molecule which are vibrating in same phaseat any moment is known as wavefront.

2. It is said that Thomas Young, who initially showed nature of light, could read by age of two and read yhe book of scriptures twice in his initial years.

3. With the present phase of innovation: It is unimaginable yo see impedance of light from two free light source.

4. In any case, it is conceivable to recognize electronically interferance of two autonomous sources, as exhibited by Brown and Twiss in 1952.

5. A monochromatic wellspring of light will give light of one and only wavelength.

6. Keeping in mind the end goal to have two coherant shafts, a solitary wellspring of light is part into two by strategy for wavefront part or ampliyude part.

7. NICOL PRISM: A nicol crystal is made by cutting a calcite precious stone unquestionably.

8. It produces captivated light similarly as plarised does.

9. PLANE OF VIBRATION: The plane inside which the vibration of the captivated light are limited is known as plane of vibration.

10. PLANE OF Polarization: A plane at right edges to the plane of vibration and going through the course of proliferation of light is known as the plane of polarization.

11. ELECTROMAGNETIC THEORY: A light wave is an electromagnetic wave in which the electric and attractive fields are commonly opposite to each other and them two thus are opposite to the heading of engendering of the wave.

12. DIFFRACTION OF LIGHT: The marvel of twisting of light waves around corners and spreading into the districts of geometrical shadow is called diffraction of light.

13. Determining POWER OF A TELESCOPE: The determining force of a telescope is characterized as the proportional of the littlest precise seperation betwen to far off items whose pictures are particularly obvious through the telescope.

14. Determining POWER OF A MICROSCOPE: It is characterized as the proportional of the littlest between two point questions whose pictures are simply determined by the obejective of the magnifying instrument.

15. Polarization: A wave showing diverse properties in various bearing is said to be captivated and this wonder is alluded to as polarization.

16. ROTATORY Polarization: The property of substance by righteousness of which it turns the plane of polarization of a plane energized light emission is known as the optical action or rotatory polarization.

17. Sub-atomic ROTATION: IT is the result of the particular revolution and the sub-atomic weight of the substance.

18. Particular ROTATION: It is characterized as the measure of pivot created by an answer of unit length containing unit mass of the optically dynamic substance per unit volume of the arrangement OR It is characterized as the turn delivered by 1mm thick quartz plate.

19. COHERANT SOURCE OF LIGHT: Two light are said to be coherantif these discharge light of the same recurrence which have consistent or same stage contrast.
