Question

an object is placed at a distance of 10 centimetres from a convex lens
of focal length 5 cm 1) draw a ray diagram showing the formation of image 2) state two characteristics of image formed 3) calculate the distance of the image from mirror

Answer 1

2)characterstics- same size as object , real image and inverted.
3)1/v= 1/f+1/u
1/v= 1/5 +(-1/10)
1/v= 1/5- 1/10
1/v = 2-1/10
1/v= 1/10
v=10 cm
