two properties of concave lens
Answers
Answer:
Both converge parallel rays to a focal point, have positive focal lengths, and form images with similar characteristics. A concave lens acts a lot like a convex mirror. Both diverge parallel rays away from a focal point, have negative focal lengths, and form only virtual, smaller images.
Answer:
If the convex lens is replaced by a concave lens , the formed image can not be received on the screen , because the incoming rays diverge after refraction .
When the position of the object is in front of the concave lens , The position of the image is before the object in the same side , The image formed by the concave lens is always virtual , erect and small .
The concave lens is known as the diverging lens because it diverges the rays after they pass through it , The image formed by the concave lens is a virtual image because it can not be received on a screen .
