Description
How do convex and concave lenses compare to each other? Have you ever used a magnifying lens to look at things far away? Did you know that some lenses flip images? Have you ever used a lens to cast an image on a wall? Watch your students become scientists as they dig into these fascinating questions.
How can you find the focal length of a lens? Does the type of lens matter? This is a super simple procedure measure a lens' focal length. Comparing lenses of different focal lengths is easy using this activity.
Questions Answered:
- How do convex and concave lenses compare to each other?
- How do convex and concave mirrors compare to each other?
- What do curved lenses and curved mirrors have in common?
- How do you find the focal length of a lens?
- How does the image from a lens with a long focal length compare to one with a short focal length?
Topics Addressed:
- Convex or converging lenses act like concave or converging mirrors.
- Concave or diverging lenses act like convex or diverging mirrors.
- Objects appear different when viewed through convex lenses depending on how you hold them.
- Convex lenses make real images.
- The focal length of lenses can be measured using their ability to make images.
- Lenses with long focal lengths make larger, dimmer images than those with shorter focal lengths.
