A student focussed the image of a candle flame on a white screen using a convex lens. He noted down the position of the candle screen and the lens as under
Position of candle = cm
Position of convex lens = cm
Position of the screen = cm
- (i)What is the focal length of the convex lens?
- (ii)Where will the image be formed if he shifts the candle towards the lens at a position of cm?
- (iii)What will be the nature of the image formed if he further shifts the candle towards the lens?
- (iv)Draw a ray diagram to show the formation of the image in case (iii) as said above.
