4. Sketch a graph of q vs. p. Also sketch a graph of 1/q vs. 1/p. Do you expect either or both of the graphs to be a straight line? If so, given the focal length f, what are the slope and the vertical and horizontal intercepts? Slope = Vertical intercept= Horizontal intercept =Equipment List . Optical bench containing: o Light source with arrow o Converging lens A A o Screen Optical Bench Meterstick Light source . Aluminum with circular apertures with arrow Meter stick . Ruler Converging Aluminum with Screen lens various circular apertures I. Predictions In this experiment, we use a light source as the 'object', a distance p from a converging lens. The image is formed on a screen a distance q from the lens. Answer the following questions, keeping inmind that the lens is converging, and the image is formed on a screen. Explain each briefly. 1. Is the observed image real, virtual, or can it be either? If either, for what range of object distancesp is the image real? 2. Is the observed image enlarged, reduced in size, or can it be either? If it can be either, for what range of object distances p is the image enlarged? 3. Is the observed image inverted, upright, or can it be either? If it can be either, for what range of object distances p is the image upright
