Please provide complete description with this question answer, thank you!

Imagine you're a brand new student at lumberjack school and haven't yet taken the splinter-avoidance class. Unfortunately, you're sent out to collect firewood before this critical training and you get a tiny splinter in your finger. Thankfully, you're also a huge physics fan so you realize this is an opportunity to analyze your favorite optical instrument: the magnifying glass. The converging lens of your magnifying glass has a label on it stating that it has a focal length of 8.7 cm. You position the lens a distance of 6.2 cm from the splinter. What is the distance between the resulting image of the splinter and the lens? Give your answer in units of cm. Do not enter the units into the answer box. Be sure to enter the correct positiveegative sign for your response based upon the convention established in our textbook. Assume the input values have a precision of three significant figures
