A method consists of finding the point of intersection of a few particular rays that diverge from a point of the object and are reflected by the mirror is called?

Concave Len is also known as ________because the light that passes through it tends to diverge at a particular point called the focal point.

the point between the center of the curvature and vertex is called?

A ________ is an optical system with two refracting surfaces.

A ray through the center of the lens is not appreciably deviated; at the center of the lens the two surfaces are parallel, so this ray emerges at essentially the same angle at which it enters and along essentially the same line.

A ray parallel to the axis emerges from the lens in a direction that passes through the second focal pointF2 of a converging lens, or appears to come from the second focal point of a diverging lens.

It is formed behind the mirror and is upright relative to the object and cannot be projected on a screen.

Convex lens is also called converging Lens because the light that passes through it tends to converge at a particular point called the focal point.

Focal length is positive if the lens is a double convex lens (converging lens).

Image height is negative if the image is an upright image (and therefore, also virtual).

Distance of the image from the lens is positive if the image is areal image and located behind the lens

Image height is positive if the image an inverted image (and therefore, also real).

Distance of the image is  negative if the image is a virtual image and located on the object’s side of the lens.

Supposed you have a concave mirror that has a radius of curvature with absolute value 20 cm. Find  mathematically the image of an object, with a height of 10cm, in the form of an arrow perpendicular to the axis of the mirror at object distances of (a) 25 cm.

s' = ?
