# Problem: Part A. Which of the following is a true statement about virtual images?  a) You cannot see a virtual image. b) A virtual image must be larger than the object c) A virtual image is formed at the position from which the rays appear to have originated d) A virtual image must be upside down. Part B. If an object is placed a great distance away from and in front of a converging lens, where will its image be formed? a) It will be a great distance away from the opposite side of the lens. b) It will be very near the focal point on the opposite side of the lens.c) It will be very near the focal point on the same side of the lens. d) A virtual image will be formed behind the object.Part C. Which of the following positions of an object will create a real image if the lens is a converging lens as shown in the video?a) This lens cannot form real image.b) The object is very far from the lens.c) The object is very near to the lens.d) The object is at the focal point of the lens.Part D. Rank the image descriptions in the order that you would observe them if you were to move an object from very fas away from a converging lens to very near it.Rank the image descriptions in the order that you would observe them, starting with the object far from the lens and ending with the object  very near the lens.
