You are provided with a rectangular glass block, two pins and a piece of white paper. Describe how you would use them to determine the refractive index of the glass using real and apparent image method. An object O is placed 15cm from a converging lens of focal length 10cm. At what distance should a screen be placed so that a focused image is formed on it? A diverging lens of focal length 37.5 cm is placed half way between the converging lens and the screen. How far should the screen be from the diverging leans in order to receive a focused image? Two lenses L1 and L2 placed 12cm from each other. The focal length of L2 is 4cm. An object 5mm high is placed 4cm from L1. Construct a scaled ray diagram on a graph paper to obtain the position of the final image as would be observed by a person on the right hand side of L2 Determine the magnification obtained by the arrangement.
