ok so here is the quesiton.. An object is loacted 3.5 cm from the optical centre of a lens. The lense produces an image of magnification that is +0.667 the size of the object a) is this lens a diverging or converging lens? explain b) Find the position of the image and the focal length of the lens using the magnification equation and the thin lens equation c) make a diagram of the situation, showing the axis of symmetry and the prinicple axis of the lens, its optical centre itrs principle focal points and the positions of the object and image Work a) diverging lens (dont know why really but ill google it) b) M=3.5/? = +0.667 So it would end up being 3.5/0.667 = 5.24? Am I correct? and i cant get anything else please help!!
