Card 1
Question: What are the characteristics of an image formed when an object is placed between F and 2F of a converging lens?
Answer: The image is real, inverted, and magnified. It is located beyond 2F on the opposite side of the lens.
Card 2
Question: What happens to the image as an object moves closer to F from 2F with a converging lens?
Answer: The image moves further away from 2F and becomes larger.
Card 3
Question: What kind of image is formed when an object is placed exactly at the focal point (F) of a converging lens?
Answer: The refracted rays emerge parallel, meaning the image is formed at infinity, and no distinct image is formed.
Card 4
Question: What are the characteristics of an image formed when an object is placed within F (closer than the focal point) of a converging lens?
Answer: The image is virtual, upright, and magnified. It is located on the same side of the lens as the object, further away from the lens than the object.
Card 5
Question: How is a real image formed?
Answer: A real image is formed by the actual convergence of light rays and can be projected onto a screen.
Card 6
Question: What is the orientation of a real image relative to the object for a single converging lens?
Answer: Always inverted.
Card 7
Question: How is a virtual image formed?
Answer: A virtual image is formed by the apparent intersection of diverging light rays (extensions of the refracted rays) and cannot be projected onto a scree
Card 8
Question: What is the orientation of a virtual image relative to the object for a single converging lens?
Answer: Always upright.
Card 9
Question: What is the purpose of the thin lens equation?
Answer: It allows for precise calculations of image position and size for thin lenses.
Card 10
Question: What is the thin lens equation?
Answer: 1/f = 1/d₀ + 1/dᵢ
