Solve the all parts of given question:
Question: A 4.6 cm long insect is perpendicular to the optical axis of a thin lens; the bug is 6.7 cm away from the lens. The lens forms an inverted image of the insect which is 1.1 cm long on a screen behind the lens. (Use three significant figures.)
Part A: How far behind the lens is the screen?
cm
Part B: What is the lens' focal length (pay attention to sign)?
cm
Part C: If the insect were instead only 0.22 cm from the lens, what would the image distance be (pay attention to sign)? cm
Part D: Could the new image be projected on a screen?
I understand the question and have the diagram all drawn out but I am not sure about how to find the answers for above question.
