mirrors : convergent mirror
lens : convex lens
Explanation:
mirrors : concave mirror gives upside down images everytime except when the object is located in front of F (focal point)
The object is located beyond C
image will be located in between the F and C inverted image. reduced in sizereal image
2. The object is located between C and F or on C
Image will be located between C and Finverted larger than the object dimensions. real image(when the object is @ C , image size = object size )
3. The object is located in front of F
image will be located behind the mirrorupright imagemagnifiedvirtual image(when the object is located @ F ,no image is formed )
lens : convex lens gives upside down images everytime except when the object is located in between in front of F (focal point)
The properties of images
varies depending on the position of the object.
distance > 2F (when the object is far away)RealDiminishedInvertedsmaller than the objectoccurs in the opposite side of the lensF < distance < 2F (object approaches the lens)RealInvertedgets magnified when approaching the focal point (Image size = object size at 2F point. this becomes gradually enlarged and get infinitely large @ F point )
distance < F (
object passes the focal point )VirtualErected Magnified occurs in the same side of the lens.(magnifying glass is one example which uses this formation, mentioned in graph 2 )
Characteristics of the images of each mirror and lens are mentioned in tables for further reference
