Focus on principal Between the main focus and the pole Performance of Concave Mirror A concave mirror is a type of mirror that is curved in the center of the center. Plus, when you look in this mirror, you will
Principal focus:The principal focus (denoted by F in the figure) is defined as the point on the principal axis where the light rays traveling parallel to the principal axis after reflection actually meet (for a concave mirror) or appear to meet (for a convex mirror). The principal focus is...
Focus: The point on the principal axis where the light rays parallel to the principal axis converge (in case of concave mirror) or appear to diverge (in case of convex mirror) after getting reflected from the mirror is known as focus. Focal Length:It is denoted by the letter ‘f’. It...
rendering The velleities of the rounded reflecting surface (It is the first mirror portrait), So that you could be fooled for a moment Before you realize the reflection Isn't yours. You feel then like one of those Hoffmann characters who have been deprived Of a reflection, except that the ...
A convex mirror of focal length f produced an image(1/n)thof the size of the object. The distance of the object from the mirror is View Solution A convex mirror has a focal length f. a real object placed at a distance f in front of it, from the pole, produces an image at ...
rays are spread out (diverge). When parallel rays of light passes through the lens, the refracted rays diverge and appear to come from one point called the principal focus. The distance between the distance between the principal focus and the centre of the lens is called the focal length.…...
When the object is very far from the mirror [The incident light rays are parallel to each other and to the principal axis). The image is at the focus, The image isReal and very tiny (dot). When the object is at a distance greater than double the focal length from the...
An object of height 4.0 cm is placed at a distance of 30 cm from the optical centre 'O' of a convex lens of focal length 20 cm. Draw a ray diagram to find the position and size of the image formed. Mark optical centre 'O' and principal focus 'F' on the diagram. Also find the...

A well-known example is the curved mirror; a spherical reflecting surface will have all the aberrations mentioned here, but a parabolic mirror will bring parallel rays to a perfect focus at the paraxial focal point, thus eliminating the spherical aberration. Headlamp reflectors in automobiles are ...
