Question

An object is placed at a distance of 30 cm from a convex lens of focal length 10 cm. list any four characteristics(nature, position,etc) of the image formed by the lens.

Answer 1

given,u =-15 cm [it is left two the lens  ]

f = -30 cm [it is concave lens ]

using lens formula  1/f =1/v-1/u

1/v = 1/f +1/u = 1/(-30) + 1/( -15)

1/v = -3/30=-1/10

therefore, v= -10

the negetive sign of the image distance shows that the image is formed on the left side of the concave lens  . Thus , the image formed by  a mirror is virtual , eect  and the same side as the object .
