paraxial rays वाक्य
"paraxial rays" हिंदी में paraxial rays in a sentenceउदाहरण वाक्य
- A "'paraxial ray "'is a ray which makes a small angle ( " ? " ) to the optical axis of the system, and lies close to the axis throughout the system.
- For paraxial rays, the sphere gives the same results as the paraboloid or the exact fourth-order surface, as can be seen by Taylor-expanding the respective equations in terms of distance " y " from the axis ( the series for the paraboloid and the fourth-order surface are of course trivial ).
