Question

define magnification state new cartesian sign convention of spherical mirror and lenses ​

Answer 1

Answer:

This sign convention is known as New Cartesian Sign Convention. Sign is taken as – (negative) from pole of a spherical mirror towards object along the principal axis. This means sign is always taken as – (negative) in front of a spherical mirror. ... Sign is taken as + (positive) behind the spherical mirror.

Answer 2

Answer:

Magnification is the process of enlarging something. Additionally, it means expanding the seeming size rather than the actual size. The size of a picture in relation to the size of the item is measured by the term "magnification."

Explanation:

• Magnified images can be produced using lenses and curved mirrors.
• The New Cartesian Sign Convention is the name given to this sign convention.
• The sign is read as being (negative) from a spherical mirror's pole toward the object along the main axis.
• This means that when facing a spherical mirror, a sign is always interpreted as being negative.
• Spherical lenses and a new Cartesian Sign Convention
• All distances are calculated starting at the lens' optical centre.
• Distances that are measured in the same direction as the light's incident beam are regarded as positive distances.
• The measurements made in opposition to the direction of the light's incidence are considered negative.
• Positive distances are assumed for measurements taken upward and perpendicular to the primary axis.
• Negative distances are assumed for measurements taken downward and perpendicular to the primary axis.

These are the new cartesian sign convention of spherical mirrors and lenses.
