light reflection and refraction

image formation by concave and convex mirror as well as image formation in concave and convex lens

concave mirror -object at infinity

position of img: at f

nature of image= real and inverted

size of image= very small

application= used inn solar furnaces

concave mirror -Beyond C

position of img: between c and f

nature of image= real and inverted

size of image= dimnished

concave mirror - right at C

position of img: at c

nature of image= real and inverted

size of image= same as the object

concave mirror - Between c and f

position of img: beyond c

nature of image= real and inverted

size of image= magnified

concave mirror- at f

position of img: at infinity

nature of image=real and inverted

size of image= highly magnified

application= used in car headlights and torchlight

concave mirror- between f and p

position of img: behind the mirror

nature of image= virtual and erect

size of image= magnified

Application= used in shaving mirrors

convex mirror- at infinity

position of img: at f

nature of image= virtual and erect

size of image= very small

convex mirror-between infinity and pole

position of img:behind the mirror

nature of image= virtual and erect

size of image= dimnished

application= used in rear view mirror in vehicles because convex mirror gives a virtual and erect and dimnished image.a large area can be seen in a small size

concave lens- at infinity

position of img= at f

nature of image= virtual and erect

size of image= very small

concave lens- between infinity and f

position of img= between f and o

nature of image=virtual and erect

size of image= dimnished

application= used to correct myopia

convex lens- at infinity

position of img= at f

nature of image=real and inverted

size of image= very small

convex lens- beyond 2f2

position of img= between f1 and 2f1

nature of image=real and inverted

size of image= Diminished

application= Used in cameras

convex lens- at 2F2

position of img= at 2f1

nature of image=real and inverted

size of image= same size as object

application= Used as erecting lenses in telescope

convex lens- between 2f2 and f2

position of img= beyond 2f2

nature of image=real and inverted

size of image= enlarged

application = used in projectors

convex lens- At f2

position of img= At infinity

nature of image=real and inverted

size of image= highly magnified

aplication = used in search light

convex lens- between f2 and O

position of img= on the same side as object

nature of image=Virtual and erect

size of image= magnified

application= used as magnify glass
