Pricey Stamp $A$ rare 1918 "Jenny" stamp, depicting a misprinted,upside-down Curtiss JN-4 "Jenny" airplane, sold at auction for $\$ 525,000 .$ A collector uses a simple magnifying glass to examine the"Jenny, " obtaining a linear magnification of 2.5 when the stamp isheld 2.76 $\mathrm{cm}$ from the lens. What is the focal length of the magnifying glass?

Okay, so this problem lens produces a ritual image with a magnification magnification off 2.5 times over stem that is held at a distance. So we have distance off the object off two point 76. Saying team enters and we want to calculate the focal length off this lens. Okay, so let's find out. How are we going to calculated focal? And by definition, the focal length should be one divided by zero plus one divided by the I out the power of minus one. But the problem here is that we do not have that the I So we're gonna use the magnification the problem gives us because we know that the magnification is just minus. Oh, dear. I divided by zero. So therefore we can conclude that he I is just miners 2.5 times two point 76 which gives us a photo of minor 6.9. Same team enters. Okay, now that we have distance of the image and in the distance off your object, that's calculate focal lens or their focal left is just one divided by 276 That's do it again greets again. So we have two point 76 miners, one divided by 6.9 all to the hour of minus one. She gives us 4.6 saying two meters, and that's the final answer to this problem thankful.
