Consider a image that is located 30 cm in front of a lens. It forms an upright image 7.5 cm from the lens. Theillumination is so bright that that a faint inverted image, due to reflection off the front of the lens, is observedat 6.0 cm on the incident side of the lens. The lens is then turned around. Then it is observed that the faint,inverted image is now 10 cm on the incident side of the lens.What is the index of refraction of the lens?

Question
Consider a image that is located 30 cm in front of a lens. It forms an upright image 7.5 cm from the lens. The
illumination is so bright that that a faint inverted image, due to reflection off the front of the lens, is observed
at 6.0 cm on the incident side of the lens. The lens is then turned around. Then it is observed that the faint,
inverted image is now 10 cm on the incident side of the lens.
What is the index of refraction of the lens?
