WRITE THE CURVED SUFACE FORMULA . EXPLAIN ITS TERMS.
2. WRITE THE PLANE SURFACE FORMULA. EXPLAIN ITS TERMS.
3. WHAT IS MEANT BY PARAXIAL APPROXIMATION.
4. WHAT HAPPEN WHEN WE CONSIDER PAXIAL APPROXIMATION CRITERIA.
Answers
Answer:
1. v = Image distance u = Object distance. R = Radius of curvature. This equation is for the case when object is placed in rarer medium and image is formed in the denser medium and it is a real image and curved surface is convex.
2. We know the normal vector of a plane and a point passing through the plane, the equation of the plane is established. a ( x − x 1 ) + b ( y − y 1 ) + c ( z − z 1 ) = 0.
3. Paraxial Approximation in Geometrical Optics
Paraxial Approximation in Geometrical OpticsHere, the paraxial approximation means that the angle θ between such rays and some reference axis of the optical system always remains small, i.e. ≪ 1 rad. ... The paraxial approximation is extensively used in Gaussian optics.
4. The paraxial approximation is used in Gaussian optics and first-order ray tracing. ... For larger angles it is often necessary to distinguish between meridional rays, which lie in a plane containing the optical axis, and sagittal rays, which do not.
