Predict/Calculate A convex lens $(f=20.0 \mathrm{cm})$ is placed10.0 $\mathrm{cm}$ in front of a plane mirror. A matchstick is placed 25.0 $\mathrm{cm}$in front of the lens, as shown in FlGURE $27-32$ . (a) If you lookthroughthe lens toward the mirror, where will you see the image of thematchstick? Is the image real or virtual? Explain. (c) What is themagnification of the image? (d) Is the image upright or inverted?

a) 16 $\mathrm{cm}$ to the left of the lensb) realc) $-0.80$d) inverted

So in this problem we have, um, object. There was a place Let's put here at a distance off 25. Same team enters throne of Excellence with focal length off 20 centimeters. So we have a focal lens off. Apprenticing team enters. And this is between the lens a tensing Tim mater's. We put a mirror. Okay, so problem ones to discover the location of the image if the images ritual or Rio, what is the magnification? So before we doing any calculation, let's think about the physics of the light rays that we should know at this moment. We know that first of all, the light race that came parallel, it's converge to the mirror. The mirror is going to reflect this light tree. You're gonna pass this fruit, d'oh the lens and keep moving. Then we have a focus here, the second type of light race we had. He enters to the focus, then goes parallel. And we can say that this point in here is where the image is going to be produced. So let's confirm all this doing the calculations. No. So, first of all, let's just cover the image produced by the lens. The distance of the image lens is just one divided by F miners, one divided by zero, all to the power of miners. One. This is going to be equal one divided by 20 miners, one divided by 25 and this one This is equal to 100 ST Emitters. But now think about we know that the image is going to be produced 100 treatment 170 meters. That, too, behind the convex lens. But after tense and team enters, we have a mirror and the mirror that we can say that the image is going to be produced a 90 ST Emitters behind the mirror. But since the mirror reflects the image he produced, his ah parent object, he produces another object that has a position off miners. 80 Because miners miners 90. The image produced by the Mirror is going to be at the position minus 90 Sink Tim enters so we can say that the distance between the object and the cove excellence is just minus 90 80 minus. A decent team enters so moving on, we can calculate the rial position of the image. She's going to be one divided by 20 miners, one divided by miners, 80 minus one. This is equals two 16. Same team enters two there, left off the lens. And we know that because the light presses the light passes for the image. It is a really image, so it's a really image because the light buses fruit. There's 16 thinkyou mentors to the left. What else? We have to calculate the magnification. Okay, so let's see. The magnification is going to be magnification of on excellence and the magnification of the mirror riches. Just the I won d I too Divided by D 01 The zero to this is 100 16 give you divided by 25 minus 80. So multiplying all this we have minors, you know point eight off magnification. Since the magnification is negative, the image is inverted and that's the final answer to this problem.
