In a darkened room, a burning candle is placed 1.50 m from a white wall. A lens is placed between the candle and the wall at a location that causes a larger, inverted image to form on the wall. When the lens is in this position, the object distance is p₁. When the lens is moved 90.0 cm toward the wall, another image of the candle is formed on the wall. Find p₁ and the focal length of the lens.
