The distance along the optical axis refers to the linear measurement from one point to another along the axis of a lens or optical system, typically measured in millimeters or centimeters. This axis is an imaginary line that passes through the center of the lens and extends in both directions. It is crucial for understanding focal lengths, image formation, and the overall behavior of light as it passes through optical elements. In practical applications, this distance helps in aligning optical components for optimal performance.

What is the first value in ordered pair and second value?

First value: abscissa, is the distance from the origin along the horizontal axis (usually the x-axis). Second value: ordinate, is the distance from the origin along the vertical axis (usually the y-axis).


In torque moment arm is a perpendicular distance between line of action of force and axis of rotation from which point of axis of rotation you measure this distance?

The arm is perpendicular to the axis of rotation. If you look at the axis along its axis it is only a point. The torque is force times distance tot that point


What lens Has an optical axis?

A lens with an optical axis is symmetrically designed, meaning that the center of the lens coincides with the optical axis. This axis passes through the center of curvature, allowing light to pass through without significant deviation. Lenses that are not symmetrical may not have a distinct optical axis.


What is the point on a concave mirror optical axis through which every light ray that travels parallel to the optical axis toward the mirror moves after being reflected?

The focus of a concave mirror is the point on its optical axis where light rays parallel to the axis converge after being reflected.


Why are light beams falling along the optical axis of the concave lens not refracted?

Light beams falling along the optical axis of a concave lens do not refract because they are already passing through the center of curvature of the lens, where the refractive index and hence the angle of refraction is zero. This means that the light beams travel straight through without being bent.
