Question

As with the problems, where applicable support each answer with detailed reasoning for credit. Do not regurgitate memorized results from problems worked in the text or The large arrow in the diagram below represents an object. The two small arrows indicate the focal of the lens. Of the following statements, which is/are true? (Circle A, B, C, D or E!) The image is to the left of the lens. The image is to the right of the lens. The image is upright and larger than the object. The image is inverted and smaller than the object. T he image is upright and smaller than the object. The image is inverted and larger than the object. I and V II and V I and IV II and IV None of these is correct. If the object distance is 30.0 cm and the focal points are 15.0 cm from the center of the lens, what is the magnification of the lens?

Explanation / Answer

For diverging lens,irrespective of the position of the object,the image forms left to the lens,always forms virtual ,upright and smaller than the object

So the true answers are

I) The image is to the left of the lens

V) The image is Upright and smaller than the object

So the correct answer is A) I and V

-------------------------------------------------------------------------------------------------------------------------------
if the lens is diverging lens

1/f = 1/do + 1/di

(-1/15) = (1/30)+(1/di)

image distance is di = -10 cm

magnification is m = -di/do = 10/30 = 0.333
