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.
- 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?
- 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.
