What is an easy definition of the optical axis?

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..


What is the distance along the optical axis?

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 difference between planets period of rotation and period of revolution?

The difference between the rotation and revoulution is that rotation is the spiinning of the planet on its axis and revoulution is the orbiting of the planet around the sun.


Do plane mirrors have an optical axis?

Yes, plane mirrors have an optical axis, which is an imaginary line that runs perpendicular to the surface of the mirror at its center. This axis is important for understanding how light interacts with the mirror, as it helps define the direction of incoming and reflected light rays. In the case of a plane mirror, the reflection occurs symmetrically about this axis, allowing for clear images to be formed.


Is sunrise an optical illusion?

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.

What is the difference between meridonal rays and skew rays?

Meridional rays are rays that pass through the optical axis of a system, while skew rays do not. Skew rays travel at an angle to the optical axis, resulting in a more complex path through the optical system.

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 difference between axes and axis?

Axes is plural; axis is singular (only one of them).


What is the graph that show is how x axis changes with y axis?

Coordinate graphing is a visual method for showing relationships between numbers.


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.


What is the difference between the x-axis and the y-axis?

the x-axis goes horizontally (like this _______ ) and the y-axis goes vertically (like this | )


What is difference between x axis and y axis?

x axis means the horizontal line and y axis means the vertical line


Differentiate between meridional rays and skew rays?

A meridional ray is a ray that passes through the axis of an optical fiber.A skew ray is a ray that travels in a non-planar zig-zag path and never crosses the axis of an optical fiber.
