se both ray diagramming and mirror equation. Use ruler for ray diagram A concave spherical mirror has a focal length of 15 cm. What is the position of the image if an object is placed 21 cm in front of it? Describe th

can you help me finding the answer for this question please  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

Question 7 Use ray tracing to determine the location of the image of this concave mirror (aka converging mirror). Indicate whether the image will be... i) real or virtual. ii) upright or inverted. iii) larger, smaller, or same size. If none of the above applies, state that and explain how you know that.
