The meaning of PRINCIPAL AXIS is the line with respect to which a spherical mirror or lens system is symmetrical and which passes through both the center of the surfaces and their centers of curvature.
principal axis (redirected fromPrincipal axes) Thesaurus Encyclopedia principal axis n 1.(General Physics) the line passing through the optical centre and centres of curvature of the faces of a lens or a curved mirror 2.(General Physics) any of three mutually perpendicular axes about which the ...
An object is placed at a distance of 40 cm on the principal axis of a concave mirror of radius of curvature 30 cm . By how much does the image move if the object is shifted towards the mirror through 15 cm? View Solution Q5 A 1 cm object is placed perpendicular to the ...
A heliostat carrying a number of mirrors has one principle axis of rotation which permits slow movement to follow the sun in azimuth. Each individual mirror has a secondary axis enabling them to turn slowly to follow elevation of the sun. A heliostat comprises a frame with a single axis of ...

Ray 1 enters the system parallel to the axis, and the lens directs it through the secondary focal point F′. Ray 3 passes through the primary focal point F, and the lens directs it parallel to the axis of the lens. Ray 2, the ray that passes through the primary principal plane, is...
Principal Component Analysis (PCA) is a multivariate analysis that reduces the complexity of datasets while preserving data covariance. The outcome can be visualized on colorful scatterplots, ideally with only a minimal loss of information. PCA applicati
In the presence of two or more non-orthogonal sets of vertical fractures, the symmetry of the medium may be approximated as monoclinic with a horizontal plane of mirror symmetry if, in the absence of fractures, the rock is transversely isotropic (TI) with the symmetry axis perpendicular to ...
