What is the ray diagram of concave lens?
A concave lens is thinner in the middle than it is at the edges. This causes parallel rays to diverge . They separate, but appear to come from a principle focus on the other side of the lens. In a ray diagram, a concave lens is drawn as a vertical line with inward facing arrows to indicate the shape of the lens.
What are the six ray diagrams of concave mirror?
To summarize
| Position of the object | Position of the image | Nature of the image |
|---|---|---|
| At C | At C | Real and inverted |
| Between C and F | Beyond C | Real and inverted |
| At F | At infinity | Real and inverted |
| Between P and F | Behind the mirror | Virtual and erect |
How many ray diagrams does a concave lens have?
Case 2 – Object is between Infinity and Optical Center
| Position of the object | Position of the image | Relative size of the image |
|---|---|---|
| At infinity | At focus F 1 | Highly diminished, Point – Sized |
| Between infinity and optical centre O of the lens | Between focus F 1 and optical centre O | Diminished |
What are ray diagrams?
A ray diagram is a representation of the possible paths light can take to get from one place to another. This is often from a source or object to an observer or screen. Light has a direction of travel, it is often useful to indicate this with an arrow on your ray.
What is concave lens and convex lens?
Lenses may be divided broadly into two main types: convex and concave. Lenses that are thicker at their centers than at their edges are convex, while those that are thicker around their edges are concave. A light beam passing through a convex lens is focused by the lens on a point on the other side of the lens.
What type of image is formed by a concave mirror?
Both real and virtual images are formed by the concave mirror. When the object is placed very close to the mirror, a virtual and magnified image is formed.
