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.
An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens or microscope..
The optical axis is an imaginary line that passes through the center of a lens or mirror, while the visual axis is the line connecting the fovea (center of the retina) to the object being viewed. The optical axis is used in optics to describe the path of light through a lens system, while the visual axis describes the line of sight in relation to the eye.
No, sunrise is not an optical illusion. It is the result of the Earth rotating on its axis, causing the sun to appear above the horizon as the Earth's location moves into the path of sunlight.
Not sure, but I think it's true
The average distance from the sun to a planet is its semi-major axis, which is the longest radius of its elliptical orbit.

A focal point is the point where reflected light rays meet along an optical axis.
depths of Field means The range of distance along the axis of an optical instrument which the object will produce a relatively distinct image

A focal point is the point where reflected light rays meet along an optical axis.
The term that indicates the point where reflected light rays meet along an optical axis is the focal point.
optical axis
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).
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
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.
The focus of a concave mirror is the point on its optical axis where light rays parallel to the axis converge after being reflected.
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.
