Find out position of image and also size and nature of image in following cases and draw ray diagrams for each of the cases:-
(1). CONCAVE LENS
f=10 cm
object distance= 10cm
(2). CONCAVE MIRROR
f=20cm
height of object=400cm
distance of object =10 cm
(3). CONVEX LENS
P=2D
object distance= 20 cm
(4). CONVEX MIRROR
f=40 cm
object size= 2cm
object distance = 40cm

Solution

U have asked to many questions simply use formula 1/f=1/v+1/u For mirror And 1/f=1/v-1/u for lens withsign convention
