Ray Optics

1. Impression OF LIGHT: Reflection of light is the procedure of redirecting a light emission.

2. MIRROR FORMULA: A condition associating u, v and f if there should be an occurrence of a mirror is called mirror recipe or mirror condition.

3. Deviation: He disappointment of the standard hub and peripheral beams to go through the same point on reflection at a round surface is called variation.

4. REFRACTION: The twisting of beam at the interface of two media is called refraction.

5. As indicated by SNELL'S LAW: The result of the refractive record and the sine of edge made by the beam with the typical at purpose of frequency is steady for a given beam in both the media.

6. Environmental REFRACTION: The refraction of light through air is called barometrical refraction.

7. Basic ANGLE: The basic point between two media is the edge of occurrence in the optically denser medium.

8.TOTAL INTERNATIONAL REFLECTION: The aggregate inside reflection (TIR) is the wonder in which a beam of light going from an optically denser into an optically rarer medium at a point of frequency more noteworthy than the basic plot for the two media is completely reflected once more into the same medium.

9. Hallucination: The locating of reversed pictures on hot still summer days is called illusion.

10. Crystal: A crystal is a bit of a straightforward medium, two of whose limits are plane surfaces, slanted to each other at a point.

11. Direct MAGNIFICATION PRODUCED BY A LENS: Linear amplification delivered by a lens is characterized as the proportion of the measure of the picture to the span of item.

12. Uprooting METHOD TO LOCATE POSITIONS OF IMAGES: If a dainty uniting lens of central length f is put between an item O and a screen at an appropriate separation, then there are two positions of the lens for which a genuine picture of the article is shaped on the screen. since to get the genuine picture of the article at an altered separation, lens is dislodged starting with one position then onto the next, it is known as the relocation strategy.

13. This strategy is utilized as a part of research facility to discover the central length of a raised mirror.

14. Comparable LENS: An equal lens is a solitary lens which delivers a picture at the same position and of same amplification as the genuine arrangement of lenses does.

15. Force OF A LENS: Power of a lens is characterized as the digression of the point by which the lens merges or wanders a light emission light it at a unit separation from its optical focus.

16. THE POWER OF COMBINATION OF LENSES: The force of blend of lenses in contact with each other is in this manner equivalent to the logarithmic entirety of the forces of the segment lenses.

17. LENS ABERRATIONS: The takeoffs of genuine pictures framed by the lens from perfect ones are alluded to as the deformities of thew pictures or all the more just lens distortions.

18. DISPERSIVE POWER OF LENS: Dispersive force of a lens can be characterized as a relative change in its central length for a given scope of hues comparing to an adjustment in the refractive file.
