- For the following lens, locate the image by drawing a ray diagram (3 rays) and describe the image as (inverted or upright, real or virtual, magnified or reduced). Converging lens a. Upright, virtual, reduced b. Inverted, real, magnified c. Inverted, virtual, magnified d. Upright, real, reducedHello, I need help with Q4 and Q5. Thank you!When considering the location of images formed by lenses, we often like to employ ray tracing diagrams. To do this we draw three rays of light and see where they intersect. 1. A ray parallel to the axis refracts through the far focal point. 2. A ray that enters the lens along a line through the near focal point emerges parallel to the axis. 3. A ray through the center of the lens does not bend. This method was shown to you in class for the following situation: An object and converging lenses with the distance to the object being greater than the focal length, do > f. object focal point do focal point Now you will complete the ray tracing diagram for an object that is closer than the focal length: de focal point image Answer the following based on your ray tracing: (a) Is the image real or virtual? (b) is the image larger or smaller than the object? focal point
