Find  the  position, size and  nature of the  image formed, using the  lens  formula

Best Answer

Ans.Sol.  Height  of the object, h1 = 4 cm

Convex lens:

Focal length, f = +24 cm

Object  distance, u = -16  cm

Image distance, = ?

Height of the image, h2 = ?

Nature of the image = ?

According to lens formula

were

The image  is formed at a distance of 48 cm from  the convex  lens.

• The minus sign for image  distance shows that  the image  is formed  on the left side of the convex  lens.

• Only  virtual image  is formed  on  the left hand  side.
